Speaking of infantry, remember that there are exactly five canon infantry(BA included) units in the whole game that can even TRY to shoot at you, so feel free to shoot the crap out of everyone else with impunity. Why no, taking a 'Mechbuster-SRM out Toad-popping is not cheating. >:D
(For the curious, the five in question are the two artillery and two AA platoons in 3085, and the Centuar BA in3145. No other infantry or BA is allowed to even attempt to-hit rolls against flying aeros. Have fun.)
There's actually 5 in TRO:3085, the complete list (For those interested):
Mechanized Field Artillery (pg.195)
Missile Artillery Infantry (pg.199)
AA Jump Infantry (pg.201)
AA Mechanized Infantry (pg.211)
Field Gun Infantry (pg.215)
This last is the one Weirdo forgot and is the nastiest, it gets 6 attacks
