Sprinting as fast as he could with all his gear, Jack reached the wall with bullets kicking up snow at his feet. He ran up to it and pressed his back against the cold metal gate. He looked up saw white-masked enemy soldiers firing their rifles above him, and threw a grenade up at them.

The cold, clear midnight air magnified the sound of the explosion, and of the screams. One of the men was blasted clear off the wall, flames licking at his uniform. He hit the snow in front of Jack hard and rolled a couple times before coming to a permanent rest.

Jack thought he'd gotten at least one more, but had other things to do than count kills. He quickly put blocks of plastic explosive into place on the gate, rigged them for remote detonation, then ran to a safe distance, still hugging the wall for cover. He hit the button as soon as he was clear. The detonation ripped a ragged molten hole through the heavy gate big enough for people to climb through, and when he went to look at it, he saw the smouldering body of another enemy lying on the other side. He'd been blown several feet away when the gate exploded.

All in all, Jack considered it a good start.
