NSDQ 

Stands for "Night Stalkers Don't Quit." The official motto of the US Army 160th Special Operations Aviation Regiment. They were founded after the failure of the mission to rescue the Iranian embassy hostages. Their sole purpose is to carry Special Forces teams into combat in Blackhawks, Chinooks, and Little Birds in all weather and usually under the cover of night while flying just off the ground to avoid detection. The NSDQ attitude is summed up by a passage from the Night Stalker creed: " I eagerly meet the enemy for I volunteered to be up front where the fighting is hard."
