I really shouldn't have let them go alone. Oh well, I guess I'll keep watch from here. This gun ain't made for me, but maybe I can make it work...
Evan gets into sniping position, on overwatch over the others, preparing to shoot whatever target is near if these two mess up.
You get on in a comfortable shooting position, making sure the rifle is steady and you've got room to aim it around. This gives you a nice overwatch of pretty much a third of the camp, including the spot where your two compatriots are hiding.
The gun itself isn't exactly a sniper's wet dream. However, at this distance it might as well be completely silent. The somewhat shoddy accuracy isn't much of problem either, since we're well within 400 meters of the camp. Nothing a man of your skills can't handle.
You set the sight and steady your breath, preparing for whatever might happen.
Is the tent empty? Does it sound empty?
Very carefully, you inch closer to the tent and put your ear to the fabric. Inside, you can hear a steady snoring. At least one guy is having a good night's rest in there.
Get ready to disable the firing pins of the next patrol.
You peek out from around the corner and wait for the next patrol to come around. They round the corner and you slowly duck back behind the tent. You make your way to the other side and peek out again, this time looking at the their backs.
Normally you'd need to touch metal to manipulate it with any kind of effeciency, but firing pins are tiny enough that line of sight and decent proximity should be enough. For dramatic effect, you wiggle your fingers and hope for the best. At first, nothing seems to have happened, but one of the guys stops and other stops a few steps later.
"hast du nichts hören?"
"Nein, warum?"
"Ich dachte, ich etwas Metallisches gehört."
"vielleicht Erik über seinen Helm wieder auf dem Weg zur Toilette ausgelöst."
The two of them chuckle, and continue on their way, oblivious to the fact that their guns cannot fire anymore.
