Squadron vehicles/helicopters

I’m currently fairly new to squadrons and I only have one squadron vehicle, the A4E. I’m about halfway through the JF 17, an wondering what I should get afterwards. I currently don’t have any helicopters, and I kind of want to try some, so I’m wondering if I should get one of the squadron ones instead of the rubbish reserve ones. However everybody tells me helicopters are pretty difficult so IDK just need some help are squadron ones worth it or not? For reference I have America air 10.3, Italy air 6.3 and China air 2.7, and limited ground in each, my highest being America tier 3

Helis depend on what you want to do with them. Play in ground RB, just learn for ground AB or grind/farm in heli PVE?

Well you are not going to grind rank 5 helis with an apache or mi24. You need to research the one that complements your lineups or doesnt have penalty research

I don’t play ground RB much and I’m probably just going to do PVE

Im going to main PVE because I don’t play ground much and only have tier three

If you plan to play PVE, some of the entry choppers are doing quite OK. The US AH-1G and Japan UH-1B can attack bases to pretty well maximize the income.
The squadron choppers all will work ok in pve. Again, it depends on what play style you like to use.

If I were to use a squadron helicopter for pve which one would you recommend? The a56 can carry a lot of rockets, would it be good for destroying bases and using its speed to cap points? Or would you go for the other 2 helps?
