War elephant
Modern era

With the advent of gunpowder warfare in the late 15th century, the balance of advantage for war elephants on the battlefield began to change. While muskets had limited impact on elephants, which could withstand numerous volleys, cannon fire was a different matter entirely – an animal could easily be knocked down by a single shot. With elephants still being used to carry commanders on the battlefield, they became even more tempting targets for enemy artillery.

Nonetheless, in south-east Asia the use of elephants on the battlefield continued up until the end of the 19th century. One of the major difficulties in the region was terrain, and elephants could cross difficult terrain in many cases more easily than horse cavalry. Burmese forces used war elephants against the Chinese in the Sino-Burmese War where they routed the Chinese cavalry. The Burmese used them again during the Battle of Danubyu during the First Anglo-Burmese War, where the elephants were easily repulsed by Congreve rockets deployed by British forces. The Siamese Army continued utilising war elephants armed with jingals up until the Franco-Siamese conflict of 1893, while the Vietnamese used them in battle as late as 1885, during the Sino-French War. During the mid to late 19th century, British forces in India possessed specialised elephant batteries to haul large siege artillery pieces over ground unsuitable for oxen.

Into the 20th century, military elephants were used for non-combat purposes in the Second World War, particularly because the animals could perform tasks in regions that were problematic for motor vehicles. Sir William Slim, commander of the XIVth Army wrote about elephants in his introduction to Elephant Bill: "They built hundreds of bridges for us, they helped to build and launch more ships for us than Helen ever did for Greece. Without them our retreat from Burma would have been even more arduous and our advance to its liberation slower and more difficult." Military elephants were used as late as the Vietnam War.

Elephants were as of 2017 being used by the Kachin Independence Army for an auxiliary role. Elephants are now more valuable to many armies in failing states for their ivory than as transport, and many thousands of elephants have died during civil conflicts due to poaching. They are classed as a pack animal in a U.S. Special Forces field manual issued as recently as 2004, but their use by U.S. personnel is discouraged because elephants are endangered.
