That guy is not holding the gun properly, plus it looks like an air soft. Perhaps the whole pic is photoshopped.
for the record the technique that man is using is a modern firing technique the rifle shooter has better control at range in auto fireing modes but it's very poor in very close quarters.
It's especial well associated with Chris Costa former president of Magpul corp and a well known Tactical trainer.
but there are a few oddity's first that man is using a G36k.
so what's a german Sub carbine often used in counter terror doing in that the same pic as a brand new non export attack helo from china?
The gloves are Oakley so are the shades.
The Chinese have too my knowledge never been shown wearing Oakley products
the camo is M81 well and the web gear is western oh and our boy here... has a camo'ed Old Glory on his chest you can see the stripes dead center. So unless this guy is Blue army and they decided too ditch the blanks and laser tag kit I am betting some one photoshoped
