Constructing "grenade fences" for the humvee turrets. The guys are rigging homemade cages that they will drape cammo netting over. This hides them from snipers and also prevents grenades from being dropped into the turret (always a bad thing). There is even a story about a poisonous snake being thrown up into a turret out in
SGT L. making sure nothing comes loose.
