Taking a page out of Hannibal’s war manual, it looks like some unit tried their hand at war-elephants and a slightly different approach to “Elephant Gun”. I am not sure what the thought was to mounting a belt-fed machine gun to the top of this Elephant. Perhaps as an alternate all-terrain vehicle that has offensive capabilities. The machine gun looks to be a “potato digger” M1895 Colt-Browning.
