Jackie the Baboon was more than just the mascot of a South African WWI regiment. He drew rations, drilled with the soldiers, spent 3 years on the front lines, saluted his superiors, lit his comrades cigarettes for them, saved the lives of infantrymen (and nursed one through dysentery), had to have his leg amputated, and received discharge papers and a military pension like any other soldier.
