Girl Back Home
It's the first rule of warfare: Never show your fellow trenchmate a photo of who you're fighting this godforsaken war for back home. Wait, no, I got that wrong. That's the second rule. The actual first rule is don't take a picture of who you're fighting this godforsaken war for at a low angle, or with bad lighting that makes the neck look weird, or when they just had dairy. The third rule is don't die, but that sort of goes without saying.
