It's illegal to maintain a native animal as a pet in a combat zone, but U.S. troops at Kirkuk Regional Air Base in Iraq quietly did just that after a three-legged dog named Tripod appeared. Her human caregivers believe Tripod protected the base from some attacks, but military animal control personnel tried to trap and kill the dog, according to this account. No fewer than 80 people at the base helped protect Tripod before she got to the U.S., where she's been adopted. "There are many amazing stories of these native dogs fighting side by side with American forces and impacting their lives forever. Let us not forget these incredible four-, or three-legged, friends," writes Andrew Edtl of the Utah Air National Guard.
