"They're warning us, they're warning us, one shell hole for just the four of us. Thank your lucky stars there are no more of us, so one of us can fill it all alone."
It startled him out of his careful watch over the metal barriers, his caution to ensure only the slightest of flesh was peeking up over the edge and under his helmet disturbed briefly. Thankful to have not been shot thanks to his comrade's singing, he snorted a laugh as he hopped back down from the ladder, dusting himself off as if to bat away being shaken.
"Captor, what the hell are you-"
"Gassed last night, and gassed the night before," a more feminine voice rang out, a wink tossed his way, broken nails lifted to lips that didn't need lipstick to look good, anyway. "Going to get gassed tonight if we never get gassed anymore!"
"When we're gassed, we're sick as we can be - For phosgene and mustard gas is much too much for me!" They sang together, laughing hoarsely despite themselves. By the next verse, he'd even joined in, a fourth voice joining their tune when the medic passed by - Certain to tilt his helmet into proper position.
"They're killing us, they're killing us, one respirator for the four of us! Thank your lucky stars that we can all run fast, so one of us can take it all alone!"
It was a bloody war, but it was a great one.
