Much of their initial preparation took place at Camp Pendleton and later in the rugged terrain of Guadalcanal . Training emphasized rubber boat maneuvers, long-distance forced marches with heavy packs, and jungle survival.
The battalion was often issued specialized or experimental gear that differed from standard infantry:
Raiders favored high-volume fire, utilizing M1918 Browning Automatic Rifles (BAR) , M1 Thompson submachine guns , and Reising submachine guns.
Some units were famously issued specialized Bergmann boots (logger-style boots) to better handle the mud and terrain of the Pacific.
Raiders were trained in silent killing, demolition, and the use of both American and captured enemy weaponry.
Influenced by Brigadier General Evans Carlson, the training fostered a unique "Gung Ho" spirit (working together), which broke down traditional officer-enlisted barriers to prioritize unit cohesion. Equipment & Weapons
