Good call, yes I can see that working well!
I find Heroes and Snipers (of any nation) pair really well togther too. Often your opponent will use a vehicle to move point-blank and flush out snipers. But with a Hero in your pocket you can deploy and move into an adjacent hex to take out the vehicle.
The paras are another obvious pairing and you’ve got some of them in your build too.
