Goal is to provide a break from serious missions, get some easy prisoners and loot. Not much more to it than that. You win by knocking out everyone. No special items or exit zones to help you. I recall someone complained about Ghosts specifically in this mission because they're resistant to daze so it took forever. At least the dress provides near immunity to their attacks and you'll also get ton of Melee XP.

I keep around old milestone saves so I took a look if I can be more specific. Seeing your squadron I think you are pretty safe to unlock "Alarmed/Angry" if you wish. I done it somewhere between Jan-Mar 2602 (as save gap indicates) and had 6 bases with each housing 1 interceptor at the time. All were Shark Jetbikes with 50mm or 30mm cannons. If there was a Predator replacing any of those it received a Plasma Charger (life saver) as well. Never had problems winning air-battles with conditions mentioned. In your place I'd wait until research list thins out a little bit just so it's more manageable, list is only gonna get nastier I can promise you that. Tech from bigger ships isn't the main bottleneck, RNG events/interrogation techs/loot is.
If by undetectable Convoy you mean because it's a ground vehicle (?) - yeah that idea don't fly. Funny enough I though the same. Enemy base radar pings every 10-15 mins or something, so ih your transport can fly the gap faster than that you can sneak in undetected.
Btw, I raided first enemy base in BLOWFISH, 8 WARRIORS inside, with Manstoppers, Cattle Prods, 2 RPGs, and several Landmines. A dumb move on my part with how little I known then (expected bandit camp base tops, got Academy instead). You need some decent gear against Provorst/Guildmaster, and bringing more Soldiers also wouldn't hurt.
