One of the benefits of using these codes derived from Native language was open-air messages could be sent faster, often in one to two minutes compared to existing encryption methods requiring up to four hours to craft, communicate and decode. NACT messages were typically brief—usually less than three lines—to avoid creating radio congestion, drawing enemy attention, providing repetition or giving the enemy more transmissions to analyze. “Whenever we sent a message it was short, sweet and to the point,” Comanche code talker Roderick Red Elk noted.
