For balance, I suggest introducing prem paratrooper units for the USA and Japan for 1-2 br. Also, 2 other factions have the opportunity to play as paratroopers on low br.
For the USA, I propose the introduction of British paratroopers with an mk5 wall (preferably with a bayonet)
For Japan- Paratroopers with type 100 Paratroopers (take out the medical squad with this weapon from sale with this)
Sten mk.V should be tech tree while paratrooper Type 100 will not be reused, that would make previous buyers angry.
Intead all factions should get paratroopers with changable primary weapons like Soviets.
Please no. We already have 2 british para squads. Also sten mk 5 should not be locked behind some limited squad. It needs to be in tt. I think french paratroopers would be better since we already have their voices in the game files and they would be more unique
