My favorite thing to do in war thunder has always been to ground pound tanks with airborne meme worthy cannons. The closest we have in enlisted is the Yak 9K (yes I have it) with its 45mm cannon. Its good against Pzr 4 and lower, but begins to struggle to deal with heavier tanks.
Possible additions to satisfy this:
Tempest V with 2x 47mm Vickers (my fav)
Hs 129 B-3 75 mm (2nd fav)
Ki-109 75mm
P.108 serie 2 102mm (least likely to be added)
PBJ-1H 75mm
Su-8 4x 45mm, but make sure its armored targets ammo
not to mention, In war thunder you have and actual big sized map, with a lot of room to maneuver, to gain altitude etc, in enlisted you dont have that, even if not for those limitations, if the duck gets a random shot of an smg the structural dmg will fuck it up so badly that it will probably go down
maybe at least for custom games it would be cool tho
