If anything, he has the element of surprise. Sowing some chaos at this point might be risky, but if Hux is pinned and out of ammo, it might give him the opening that he needs. 76 keeps moving in, picking off soldiers where he can and trying not to stay in one place too long as he makes his approach. It's only a matter of time before he can engage them directly.

Which he does--outright grabbing one from the back and flinging him aside as he bodily clears a path towards the dugout. It's here where 76 is able to showcase the full extent of his abilities, taking on the soldiers hand to hand, simply because it's easier than taking the time to reload his rifle. Luckily, he has enough of the element of surprise to keep from getting shot at, though he's not exactly stealthy and the Turks figure out what's going on after the first few men go down.

But 76 pushes through anyway, announcing his arrival with a soldier literally thrown into the wall of the dugout.

Surprise.
