The M41 Walker Bulldog remains in service in some countries to this day.

The story behind the answer

True. Although the U.S. retired it decades ago, the M41 Walker Bulldog—introduced in the early 1950s—remains in limited service with a few militaries, often in upgraded forms. Taiwan’s M41D program added a diesel engine and modern sights, and Thailand has kept Bulldogs in second-line roles, showing the type’s staying power.

Designed to replace the M24 Chaffee, the M41 was a fast, 76 mm-armed light tank for reconnaissance and fire support, widely exported during the Cold War and used heavily by South Vietnam. Its rugged, simple design makes it easy to keep running—think of it as the “pocket rocket” that outlived its era.
