I think I achieved school bus, snitches get stitches, and back and to left award.
On Keren, I killed someone who was driving a truck out of the upper British outpost from one of the hills in B+2 I suppose. With a Carcano carbine, without aiming down the sights. Just a random shot, and what do you know, it actually hit a moving target far away
My suggestion would be the
Unexpected Death from Above award; Kill someone with a Ju52.
Or a
Size Matters award; kill an AT rifle dude from far away with a pistol.
