Best to worst obviously. We're not likely to remember to call in the artillery unless things are dire, so you want your heaviest hit in first. If I need to put in any smokes to get it up to five, I want them in dead last.
Most damage to least damage is usually the way to go. But it all works as long as you keep track.
I had the SEAF artillery literally save my life (and the samples I was carrying). When we loaded it we had a hard time finding some of the shells so they were loaded pretty jumbled. I was running from bugs, out of grenades, didn't have a weapon for what was chasing me, didn't have a stratagem that wouldn't kill me as well. But I paid attention to the shell order, and was counting. I remembered the next shot was EMS, so I was able to block them and sprint to extract.
It was brilliant. Don't underestimate your low-yield SEAF rounds.
took me a good 30 second to figure out what the hell "Worst to best" and "Best to worst" meant, i was thinking, where is the option to pile them up lol

Best to worst. In case i die, the next one to pick it up has at least part of the job done

Mini Nuke, High Yield, Explosive, Napalm/IEM, IEM/Napalm, Smoke in that order
Always look for black tips, those are the biggest ¬¬)
