ISIS had no chance to fire RPG .
ISIS with RPG VS US sniper with one shot one kill . Nobody dare
to explore thelves.
Don't shoot at the head because of the hammett don't shoot
at the body because of bullet proof vest so shoot at the foot.
Don't mess with US marines , they don't run away
and abandoned their weapons like Shiite Iraq and
Afghanistan soldiers who run away and abandoned
their weapon before the fight even start. Iraqi Shiite
soldier are like south Vietnamese soldiers , they are
coward, they abandoned their weapons and surrendered
then they all were executed by ISIS.Only the Kurdish
female fighters stand their ground and with to death
with honor rather to behead by ISIS.
