Military Unit Name Generator

Real military units carry two names: an official designation and a nickname the soldiers actually use. The official form is number plus type plus branch, as in 1st Cavalry Division, 75th Ranger Regiment or 2nd Battalion, 5th Marines, and higher formations often add a heraldic identity such as the Big Red One, the Screaming Eagles or Hell on Wheels. British and Commonwealth regiments swap numbers for tradition, so you get the Coldstream Guards, the Black Watch, the Gurkha Rifles and Princess Patricia's Canadian Light Infantry, each with centuries of battle honours behind it. Special operations forces tend to be terse and slightly mysterious: Delta Force, Sayeret Matkal, GSG 9, Vympel.

The nicknames follow their own logic. Some come from insignia (Blue Spaders, Red Tails), some from a battle (Rock of the Marne, Currahee), some from an enemy's insult adopted as a badge (Devil Dogs, Desert Rats, Old Contemptibles), and some from a founder (Merrill's Marauders, Popski's Private Army). This is why invented units feel thin when they are just Adjective plus Animal: the best names imply a history.

The list above gives you real formations from antiquity to the present, their nicknames, and a set of original units built to the same patterns, including regional regiments (Redwater Lancers, Coldharbor Dragoons) for fantasy or alternate-history settings. Use the official form for briefings, maps and orders of battle, and the nickname for dialogue and patches.
