someone said Russia need an air superiorty fighter well Su-47 Berkut i know its a prototype but still an awsome looking plane and a good one,
As for a special forces rifle:
Magpul Masada the most customizable rifle in the world (as far as i know)
the isreali Tank Merkava Mark IV nice in dessert terrain atleast its engine dosent get sandblasted and ruined :P
and ofcourse the stryker.
And a heavy sniper rifle for taking out cars and lightly armored ones hehe not a 50 cal but a 25 mm XM109
