Commando refers to a soldier specially trained for quick, dangerous missions behind enemy lines. Commandos are elite troops who can move fast, strike hard, and disappear before the enemy knows what happened. During World War II, British commandos became famous for sneaking into enemy territory to sabotage bridges, gather intelligence, or rescue prisoners. These soldiers trained harder than regular troops, learning skills like rock climbing, small boat operations, and hand-to-hand combat.

British forces adopted the term during World War II, and it spread to other militaries around the world. American Special Forces, Navy SEALs, and Army Rangers perform similar commando-style missions today.

In movies and books, commandos are often depicted rappelling from helicopters, swimming ashore at night, or completing impossible missions that regular soldiers couldn't handle. Real commando work requires extraordinary physical fitness, mental toughness, and the ability to think clearly under extreme pressure.
