I am from holland the harrier could be nice but this is mainly an infantrie game. so the BRDM1/2/3 and the M2 Bradley would be a good adition.
new guns could also be good, more units for resistance, some more civilian things such as WOMEN!!!, also a bit more for the russians.
But I still think we need some more boats cuz it is an island and how the #### did they get there in the first place!!!
