Spot the differences

i love this puzzle too~!~

the man's forehead~~
the word "IRAQ" on the left flag~~and "IRAN" on the right
the shirt of the second man from left
what's that on the right bottom ?~~
in the middle~~a woman on the left picture~~a man on the right picture
it seems the ammunition clip on the left gun is shorter and more blended~~the right one is longer and more straight

and what else??~~
