Wounded. It's the same as useless and that's the same as dead. The bodies littering the floor around him are proof of his success. The current lull between the protesters and the military won't last long and the Drone is thankful that if this is to be his last assignment that it was here in Yemen were every one of his skills had been put to use. He picks himself up swaying as the vertigo threatens to put him to the floor again.
No, dying here would be a failure and that is the one thing the Drone is not prepared to face. He makes it out and disappears into the night. If he survives he will make his next transmission. If he doesn't another unit is prepared to take his place.
