For more than a century, soldiers have marched, ridden, driven, and flown to Camp Bullis to practice tactics and marksmanship. Camp Bullis was established in 1906 because the modern artillery and small arms could not be fired safely within Fort Sam Houston. The camp expanded during both world wars to accommodate even more powerful artillery and the tens of thousands of troops being mobilized. Between these two wars, the movies Wings, The Big Parade, and The Rough Riders were filmed there. The Army's changing needs would transform the type of training conducted at Camp Bullis. Today, soldiers, airmen, sailors, and marines still go to Camp Bullis to practice not only tactics and marksmanship on state-of-the-art ranges and simulators but also lifesaving medical techniques, demonstrating once again that a good range is essential.
