The one on the right. Seems to be a short barrel sniper rifle, given the scope and the necessity of carrying a carbine in addition to it… it is magazine fed, or is that chain fed in a clear cover? No rail system, no special gadgets I can see.
Israeli military. Nothing else I can see suggests it us otherwise. You only carry two weapons if the have separate capabilities, snipers usually carry standard issue shortrange weapons on them for when they have to engage short range, and usually has one to three guys attached to them for sighting and covering their flanks, or radio.
He isn’t in a standard infantry stance either, unless your stabilizing for a long range shot. Fact he is farther from the wall, and aiming perfectly horizontal, and his support is along the wall suggests he was the second in, and that a hallway or low window exists there… Otherwise the rifleman to his right would be crossing his lane of fire. The spray can art in the background suggests outside, but that would be moronic, as his rifle support is on the wrong side, despite having a slight advantage in seeing someone wind around the corner first, that’s less than a second and that person winding around would see the sniper and engage him first… this is especially a issue if this person is slowly taking the corner, not exposing himself or his barrel… He would see the sniper first, not his rifleman support.
It is harder to train a sniper than a rifleman, so I’m stumped why if he is sniper, why the rifleman hasn’t prepositioned himself to the other side?
So I guess that isn’t a sniper rifle… but if not, what is it? Why you need a scope and a additional rifle if that isn’t the case?
Fact his support is kneeling in front a stairwell is idiotic by the way… but apparently Israeli Special Forces think this is awesome to do.
