2nd Lt. Jason Draper and Capt. Morad Murad, both from the 321st Missile Squadron, prepare to turn the launch key during a Simulated Electronic Launch-Minuteman, Sept. 21, 2021 near Pine Bluffs, Wyoming. SELM The test demonstrates the missile wing’s immediate nuclear response capability serving the nation, reassuring allies and deterring adversaries. As a live-fire test of the ICBM is impossible, the execution of exercises like SELM and Glory Trip help Air Force Global Strike Command provide a demonstration of the weapon system’s capability. (U.
