Lashkar impossible to win

[USMC scout sniper]

I get to the last flag, capture it,then they re spawn north of the farm. I tried 4 bricks of C4 to destroy the forward outpost and still, WTF!!!!!!!!!! ??:

The last spawn is static and the Taliban should be bleeding out, it's pretty much just a fragfest there til it ends, so set up a mortar/.50 cal and enjoy?
