I'm not a weapons expert so I'm sorry about that, but what about everything else. Please rate it
a lot of them looks stiff and unnatural
look at the guy standing to the right inside the closest boat. he's supposed to be running, but instead he looks more like he's standing on his tip-toes. the guy beside him isn't much better. the one jumping out of the boat looks instead like he's being abducted by aliens judging by how his gun doesn't appear to have any weight
a bunch of the guns have some clipping issues with their arms (one of the guys walking out of the 1st boat has it through his forearm)
your settings are pretty bad for a picture like this, what with how there are no shadows and the lack of AA makes the look very videogame-y
the guy far away laying down has some arma-level abs to be leaning up like that with a gun that heavy. with no shadows, it hard to tell if he's leaning on the sand or the barrel of the gun
the gman out in the distance kinda takes away from the whole thing more than it adds a little easter egg, but thats an extremely minor gripe
the dudes standing outside of the second boat look completely calm despite their brothers-in-arms lying dead in the water around them and further into the beach. for what it's worth though, they're posed pretty well.
My advice to you, turn up your setting to max before you take a screenshot. We wont be able to notice your framerate in a still image.
All and all, 5/10. It's a pretty good idea and you have the right props to do it. The minor details really make it hard to enjoy though.
