Some of David's recent missions include Burma with the Karen Army, Thailand, Nicaragua with the RAMA Indians, Costa Rica, Japan Tsunami Recovery Operations, and Alabama Tornado Relief Operations. In 2010 David was selected as the chief of security for the Utah Hospital Task Force for post Earthquake Haiti. His duties included protection of the Task Force Commander, a former advisor to President Reagan, as well as ensuring the protection of 120 doctors, nurses and translators. This event was the largest loss of life in modern recorded history.
David has consulted on some motion pictures and even rolled in as a commando in the 11th hour by John Lyde.
