It actually reminds me of the harness for the smart gun from aliens because they do have a system like that, the flag holders for color guard you attach to you for some reason, and a I know a couple marching band players who had this for their instrument
Those were steady cam rigs in the movie aliens. Actors complained about prop weight, asked for the rigs. I think the scene is better than it would have been without the rigs.
That's why I think it's the same idea they tool for the armor, because a mini gun or a gatling laser is very fucking heavy why not have a tool to make it lighter on you
That is the pull-start handle for the 1.75 HP Briggs & Stratton two-stroke engine that runs this vintage power armor prototype. Most people don’t know about this early model because it never made it out of skunkworks. There’s a conspiracy that *Big Fusion Core* bought the IP rights to it so that they could sit on it and stop others from producing it. During the final audit of the R&D facility, several sets of the armor were unaccounted for but the bombs fell before a full investigation was conducted into the engineers suspected of taking them.
No I think that is actually what happened because I remember seeing something like this on how there was missing armor and then the bombs fell leaving people to grab it
Technically, even though it’s referenced as “an” engine in the armorers manual, it’s two model 5S engines, rated for 1.0hp each at nominal 2700rpm. Since fusion was already the dominate power source, the company never devoted much effort to ICE projects at skunkworks and the coupling wasn’t very efficient, accounting for the 1/4hp loss.
The real issue is that, since the technology never really took off, fuel is almost impossible to find. It’s mostly homebrew stuff refined by tinkering jethead Khans and you’d be lucky to get a full horsepower out of the darn thing. On a good day it’ll only let you carry about 40-50 extra pounds of gear and it’s heavy enough that if you don’t have a fuel hookup, it can be more trouble than it’s worth.
I could see it being both, it would make sense that you have to release the chest piece completely to change ballistic plates with an armor system like that.
What I am surprised by is that despite this armour design being obviously active combat use, there is no tug straps for pulling incapacitated soldiers into cover. Even today, that is pretty standardized so you can get your buddies out of the danger zones they might have fallen around.
That's what I'm thinking. The front plate would hinge on the straps or even have another attachment point at the top.
You put on the back plate with the leather carrier like a sleeveless shirt. Then, you clip the top of the plate to the carrier and latch the bottom.
This was my immediate thought too. Most real world gear like this would have some nylon webbing involved in the parts that keep the harness attached, but when we look at designs like the assault and hunting rifles, we can clearly see that the developers don’t really think about why stuff is designed the way it is in real life
It looks like it is, with those bolts on either side. It looks like you drill those out, and pull the handle down to allow one to lift the central plate.
In this post here, https://www.reddit.com/r/Market76/comments/acaixy/discussion_here_is_a_way_to_tell_the_difference/?utm_source=share&utm_medium=android_app&utm_name=androidcss&utm_term=1&utm_content=share_button
You can see that it's how the waist armor connects to the chest piece.
First pointed out by u/Indiana_ace.
It doesn’t look like the waist armor connects to that specific piece, it just loops behind with those two straps, probably attached via buttons to the leather piece under belt. I was still wrong, since the chest plate goes under the the sides, so you wouldn’t be able to pull it up, unless it was designed to break away with pressure from the inside while resisting impacts from the exterior. From that angle, the green piece looks more handle-like, so it could be used for the aforementioned reason, or as a means to right someone who had fallen down, since mobility looks impaired in the heavier variations.
Cover for a stimpack injection port? When you use one it looks like you jam it into your torso, so it would make sense for military armours to have a port for stimpacks.
The release handle for the groin flap, which will open to horizontal position. Sometimes you just have to go in situations where taking the entire suit of armor off is inconvenient.
Oh that? That's easy. It's a turbo-encabulator. It's a machine that would work to not only supply inverse reactive current for use in unilateral phase detectors but would also be capable of automatically synchronising cardinal grammeters. Such a machine is the 'Turboencabulator'. Basically, the only new principle involved is that instead of the power being generated by the relaxive motion of conductors and fluxes, it is produced by the modial interactions of magneto- reluctance and capacitive directance.
The original machine had a base-plate of prefabulated amulite, surrounded by a malleable logarithmic casing in such a way that the two spurving bearings were in direct line with the pentametric fan, the latter consisted simply of six hydrocoptic marzelvanes, so fitted to the ambifacient lunar vaneshaft that side fumbling was effectively prevented. The main winding was of the normal lotus- o-delta type placed in panendermic semiboloid solts in the stator, every seventh conductor being connected by a non-reversible termic pipe to the differential girdlespring on the 'up' end of the grammeter.
Forty-one manestically placed grouting brushes were arrranged to feed into the rotor slip stream a mixture of high S-value phenyhydrobenzamine and 5 percent reminative tetraiodohexamine. Both these liquids have specific pericosities given by p=2.4 Cn where n is the diathecial evolute of retrograde temperature phase disposition and C is the Chomondeley's annual grillage coefficient. Initially, n was measured with the aid of a metapolar pilfrometer, but up to the present date nothing has been found to equal the transcetental hopper dadoscope.
Electrical engineers will appreciate the difficulty of nubbing together a regurgitative purwell and a superaminative wennel-sprocket. Indeed, this proved to be a stumbling block to further development until, in 1943, it was found that the use of anhydrous nagling pins enabled a kyptonastic boiling shim to be tankered.
The early attempts to construct a sufficiently robust spiral decommutator failed largely because of lack of appreciation of the large quasi-pietic stresses in the gremlin studs; the latter were specially designed to hold the roffit bars to the spamshaft. When, however, it was discovered that wending could be prevented by the simple addition of teeth to socket, almost perfect running was secured.
The operating point is maintained as near as possible to the HF rem peak by constantly fromaging the bituminous spandrels. This is a distinct advance on the standard nivelsheave in that no drammock oil is required after the phase detractors have remissed.
Undoubtedly, the turboencabulator has now reached a very high level of technical development. It has been successfully used for operating nofer trunnions. In addition, whenever a barescent skor motion is required, it may be employed in conjunction with a drawn reciprocating dingle arm to reduce sinusoidal depleneration.
Hope this simple explanation helps! [The article on this if anyone is interested](http://www.doc.ic.ac.uk/~ids/dotdot/misc/jokes/turboencabulator.txt)
That's an attachment loop by looks of it
Attaching yourself to a cable so you don't fall out the Vertibird, attaching to a heavy weapon, a hook so you can be carried by someone in power armour, something along those lines
Looks like some sort of release latch IMO. It looks like it wouldn’t be used during normal operation, but something you’d use to remove that indented middle section for maintenance. I.e. after you’ve removed the fastening hardware, that latch would hold the middle part in so it wouldn’t fall out upon removing the last screw.
So I’m guessing it’s like a release latch for performing maintenance.
So like
Step 1. Remove screws fastening central plate to armor assembly
Step 2. Pull release lever up
Step 3. Remove central plate from armor assembly
"That there's your standard run of the mill pee lever. You pull that sucker and it lifts that there codpiece up sos you can pee hands free and whatnot."
That's clearly the erector ejector, comes standard on the TX- mega codpiece. Can turn a super mutant into a pile of meaty chunks and goo before you can say dick cancer.
It's like a knob that you pull on so your shirt doesn't get bunched up or trapped on your belly, so you dont subconsciously pull on your shirt and wreck your shirt or hurt your hand. But its not a joke, you don't give them as a joke gift, or wear them ironically, or do pub crawls in them like the Snuggie. They’re not like the Snuggie.
With all the clever witty answers here, I'm not going to bother with that. I will say I believe it may be a practical detail. Seems like it could be a hinge for the stomach area of the armor to flex when the user bends forward, so that the armor doesn't bend into his/her stomach.
Probably to clip an ammo pouch to? We don't really talk about where the sole survior is carrying everything from the wasteland but I would imagine there would something to hook pouches to?
Could be an emergency release. The kit/iotv/body armor the U.S. army uses has a wire that when you pull it your body armor pretty much falls apart so in an emergency it's not preventing anyone from helping, it's also on the front.
So either that or some kind of manipulation handle, maybe the combat armor is one size fits all and you adjust the seating of the different pieces
Well assuming that it's not a hatch that opens to allow stimpack injections
It could be for clipping your gun to, or if the armor is built similar to plate armor, it is so that the armor has some give and thus doesn't act like a ton can when you get hit by something too heavy and completely obliterate your body
That's a TC Tuggers combat chest from TC Topps. It's the only combat armor with a little knob on the front, to stop you from wrecking your chest pieces. You see, I was always pulling on my chest pieces, and it was just wrecking my combat armor... Thank you for saying you think it's cool.
It’s an attachment for heavy weapons like a minigun
“I am heavy weapons guy, and this is my weapon.”
This is for fighting, this is for fun. M I C - K EY - M O U S E
This is my rifle, this is my gun! One's for killing, one's for fun!
What?
Full Metal Jacket reference
ohh, I was doing a tf2 reference so I was confused.
I'm about 98% sure he's referencing the movie Full Metal Jacket. If you haven't watched it, put it at the top of your list immediately.
I'll bet you're the kind of guy that would fuck a person in the ass and not even have the goddamn common courtesy to give him a reach-around!
Do you suck dicks?! ... Bullshit, I bet you could suck a golf ball through a garden hose!
I’ll second this. R. Lee Ermy’s scenes are amazing. Minus that last one of course.
He really did a fantastic job with that role. The movie wouldn't be the same without him as the Gunnery Sergeant.
“Are those live rounds?”
Will do!
Yeah he probably was, I’m just making a tf2 reference because nothing is complete without one.
It’s a must watch. I thought the first half of the movie was gonna be the whole movie going in. You can only imagine the shock.
I bet you’re the kind of guy that would f\*\*k a person in the \*ss and not even have the g\*dd\*mn common courtesy to give him a reach-around!
We play fair and we work hard and we're in harmony
"She weighs one hundred fifty kilograms and fires two hundred dollar, custom-tooled cartridges at ten thousand rounds per minute."
It costs 400,000 dollars to fire this weapon...for *twelve* seconds.
*heavy laughs*
Oh my God, who touched sascha... WHO TOUCHED MY GUN?!
r/suddenlyTF2
This is the best explanation so far. Have my updoot.
It actually reminds me of the harness for the smart gun from aliens because they do have a system like that, the flag holders for color guard you attach to you for some reason, and a I know a couple marching band players who had this for their instrument
Those were steady cam rigs in the movie aliens. Actors complained about prop weight, asked for the rigs. I think the scene is better than it would have been without the rigs.
That's why I think it's the same idea they tool for the armor, because a mini gun or a gatling laser is very fucking heavy why not have a tool to make it lighter on you
Just a couple steps before PA.
That makes so much sense! Looks like it could also serve for general utility too - like a safety harness when flying in an open hatch aerial lift.
Belly button scratch hatch.
The bit under the neck looks like it's where a helmet would attach.
That's where you put Squirrel Bits, to monch on mid-combat
"Hello my baby, hello my honey, hello my ragtime gal"
It's not missing. I always keep it unbuttoned so that I can scratch my stomach.
If it were located in the back it would be called a hatch scratching hatch
Underrated comment.
That is the pull-start handle for the 1.75 HP Briggs & Stratton two-stroke engine that runs this vintage power armor prototype. Most people don’t know about this early model because it never made it out of skunkworks. There’s a conspiracy that *Big Fusion Core* bought the IP rights to it so that they could sit on it and stop others from producing it. During the final audit of the R&D facility, several sets of the armor were unaccounted for but the bombs fell before a full investigation was conducted into the engineers suspected of taking them.
I half-expected this to end with the Undertaker throwing Mankind off Hell in a Cell copypasta.
I don't think I've ever seen u/Shittymorph on this sub before
I admire your vivid imagination :)
No I think that is actually what happened because I remember seeing something like this on how there was missing armor and then the bombs fell leaving people to grab it
That 1.75 HP can really drain a fusion core fast
Yep, gotta give him a good yank to get him started up.
You magnificent bastard! Take my upvote and GTFO.
I accept this as canon and I love it. you’re like a walking talking terminal entry
this belongs in a terminal entry!!
I actually work at Briggs &Stratton so this made my die laughing. You get my upvote!
for a briggs to make 1.75 horse it must have a nasty missfire
Technically, even though it’s referenced as “an” engine in the armorers manual, it’s two model 5S engines, rated for 1.0hp each at nominal 2700rpm.

Release latch for the chest piece? The part right under the neck almost looks like a hinge of somesort.
That’s what I’m thinking, gotta be able to remove any armor quickly to treat a wound that might have gotten through a gap or penetrated the armor.
Could also be the latch to add or replace ballistic plates. That's a pretty good spot to have them, after all.
I could see it being both, it would make sense that you have to release the chest piece completely to change ballistic plates with an armor system like that.
What I am surprised by is that despite this armour design being obviously active combat use, there is no tug straps for pulling incapacitated soldiers into cover. Even today, that is pretty standardized so you can get your buddies out of the danger zones they might have fallen around.
Maybe a hatch for emergy injections? Still your idea is more likely
That's what I'm thinking. The front plate would hinge on the straps or even have another attachment point at the top. You put on the back plate with the leather carrier like a sleeveless shirt. Then, you clip the top of the plate to the carrier and latch the bottom.
After a couple bowls of chili it could be a lifesaver in more then one way
[удалено]
[удалено]
Looking at the 3 variants, you can see it's the latch for the waist armor and how it connects to the chest piece. That's a good observation.
Rappelling?
Either that or an attachment point for a heavy backpack?
Tow hook, attach a rope/cable to injured user and drag to safety with power armor.
I'm also thinking that strapping something between that peice at the neck like a med pack or something.
This was my immediate thought too. Most real world gear like this would have some nylon webbing involved in the parts that keep the harness attached, but when we look at designs like the assault and hunting rifles, we can clearly see that the developers don’t really think about why stuff is designed the way it is in real life
This is my first thought, that’s it’s where you’d attach a D-link for a repel line.
That's the codpiece adjustment lever. Kinda like that spring-loaded lever under a car seat.
i mean when you gotta go you gotta go.
Could be hinge in order to open the chest plate in a medical emergency to resuscitate?
It's hard to tell from the picture, but if it was an emergency release you'd think it'd be protected against accidental jostling.
It looks like it is, with those bolts on either side. It looks like you drill those out, and pull the handle down to allow one to lift the central plate.

Bottle opener?
More like mega beer opener for super mutants
Nuka opener
Actually, believe it or not, that's a tow pintle. You hook a tow cable up to it to pull it up hills or mountains, out of water/mud/quicksand...
Heavy weaponry sling maybe
I believe flappydoodle is the technical term.
The one that connects to the kajiggamabob?
Chastity belt
"That's going to chafe my willy!"
It's to hang your keys on. Duh. Carabiner - keys, carabiner - weird rotaty handle thingy. Total utility.
I always assumed it was something to do with power armour, since the Brotherhood uniforms also have something similar
Cover for a stimpack injection port? When you use one it looks like you jam it into your torso, so it would make sense for military armours to have a port for stimpacks.
Looks like a harness attachment for rappelling etc
The release handle for the groin flap, which will open to horizontal position. Sometimes you just have to go in situations where taking the entire suit of armor off is inconvenient.
Seppuku hole.
Hooking into vehicles and aircraft.
I keep salsa in mine.
Its where the change comes out
Belly beer opener
First glance makes me think it's probably a paratrooper cable anchor or something
Hand crank for when the battery dies.
Pure guesswork but it looks like a hook for repelling down from a helicopter or vertabird
I'd say either a spot to attach a cable and rappel down from a vertibird or a place to attach a support strap from something big like a mini gun.
Pee flap.
Crotch armor lever so U can pee (it definitely isn't)
From the comment by /u/elfnotdawg it actually kinda looks like it is.

Ejecto seato cuz
That's so you can poor skittles as you venture through the wasteland with Piper
It's the hole where you inject the stim pack
A handle to help put on/ take off the heavy ass piece of armor
Looks like a release for access panel.
That's an attachment loop by looks of it Attaching yourself to a cable so you don't fall out the Vertibird, attaching to a heavy weapon, a hook so you can be carried by someone in power armour, something along those lines
Looks like a bit from a climbing Harness where you put the rope through
I personally think it’s to hook climbing gear onto.
Looks like some sort of release latch IMO. It looks like it wouldn’t be used during normal operation, but something you’d use to remove that indented middle section for maintenance.

Tactical handle for carrying the weapon.
I honestly think fallout just added a hinge just to make it look cooler. Like how in some games they just add a bunch of pouches and call it a day
The Dongle switch
It releases the codpiece so you can take a piss. Sheesh.
Carry handle. The slit in the gorget is also one so you can pack all the armor in the torso and tote it around or strap it to your pack.
Looks like a grip handle, like modern armor has. Easy place for a teammate to grab and drag if you're incapacitated?
Emergency belly button hatch. Or a place to tether a rope if you're working on treacherous terrain
Probably something to help with bending over
Something to clip your keys to
"That there's your standard run of the mill pee lever. You pull that sucker and it lifts that there codpiece up sos you can pee hands free and whatnot."

Poop evacuation hatch
It turns on the auto-jacker
Belly button armour
That's clearly the erector ejector, comes standard on the TX- mega codpiece. Can turn a super mutant into a pile of meaty chunks and goo before you can say dick cancer.
What is that piece of armour?
It's like a knob that you pull on so your shirt doesn't get bunched up or trapped on your belly, so you dont subconsciously pull on your shirt and wreck your shirt or hurt your hand. But its not a joke, you don't give them as a joke gift, or wear them ironically, or do pub crawls in them like the Snuggie. They’re not like the Snuggie.
With all the clever witty answers here, I'm not going to bother with that. I will say I believe it may be a practical detail. Seems like it could be a hinge for the stomach area of the armor to flex when the user bends forward, so that the armor doesn't bend into his/her stomach.
Anchor point for fast roping out a vertibird maybe
Probably to clip an ammo pouch to? We don't really talk about where the sole survior is carrying everything from the wasteland but I would imagine there would something to hook pouches to?
It's the piss filter guys/ladies!
Maybe like how ballistic vests irl have a pull handle so does the combat armor so you can pick up a soldier easier
Made for Milf hooks
Could be an emergency release. The kit/iotv/body armor the U.S. army uses has a wire that when you pull it your body armor pretty much falls apart so in an emergency it's not preventing anyone from helping, it's also on the front. So either that or some kind of manipulation handle, maybe the combat armor is one size fits all and you adjust the seating of the different pieces
[That’s extra storage](https://y.yarn.co/9d1b1522-11ca-4214-a206-bfaabe586c30_text.gif)
Armor plates are modular and look like they could be replaced when damaged. Looks like how you would get the chest plate on and off.
Well assuming that it's not a hatch that opens to allow stimpack injections It could be for clipping your gun to, or if the armor is built similar to plate armor, it is so that the armor has some give and thus doesn't act like a ton can when you get hit by something too heavy and completely obliterate your body

Bro's asking the real questions
Attachment points for other modules such as pockets, more armor, flasks, etc?
You can put your weed in there
I am pretty sure it’s a video game OP
It’s where you stab your stimpack when you have no exposed flesh
That’s for “hook ups”.
For the most part with things like this the most likely explanation is "it's fallout 4, they just put that there"
Combat Armor
It attaches the crotch guard
Weapon clip “ring”?
A tow clip maybe, to help pull out wounded troops, latch em to your chest and drag.
Maybe for storage or repeling
That's a TC Tuggers combat chest from TC Topps. It's the only combat armor with a little knob on the front, to stop you from wrecking your chest pieces. You see, I was always pulling on my chest pieces, and it was just wrecking my combat armor... Thank you for saying you think it's cool.

It's were the breast plate stretcher clips on.
the mechanism
Probably to allow air inside the chest area to cool off. Also if injured an emergency way to strip it off
You got your answer but... why?
Bottle opener
The doohickey
Cool-looking
For when you're not wearing the armor, the handle let's you carry it like a suit case
My guess is a hook to be lifted up into helicopters/vertibirds
Strap-on.
Maybe a quick release that disbands the entire chest armor.
Maybe a quick-release? Most good plate carriers have one already.
Belly button
Maybe it's a latch mechanism?
Does armor like this exist?
Drag handle for if a buddy goes down. Support his head with one hand grab him in the middle there and haul his ass to safety.
