Border agents patrolling near the U.S.-mexico border fence last week was an unlikely sight: a live, unexploded World War II-era ammunition round.

The agent, who was assigned to the Brian A. Terry Station in Bisbee, Arizona, found a non-exploded MKII 37mm ordnance round, U. S. Customs and Border Protection said Tuesday.

A safety perimeter was established around the ordnance round and a pilot with the Explosive Ordinance Disposal Unit from Davis Monthan Air Force Base responded to the scene Tuesday.

After confirming it was a live round, the pilot exploded at his place.

The MK2 37 mm round was used by the 37 mm Gun M3, the first dedicated anti-tank gun fielded by the USA and first introduced in 1940. It became the standard anti-tank gun of the U.S. infantry as the size allowed to be pulled by a jeep.

The U.S. Army used the 37 mm anti-tank gun M3 during the second world War, especially in the Pacific ocean.

However, it was useless in the fights in Europe because of the rapid improvement of German tanks and, in 1943, was gradually replaced by the more powerful British-developed 57 mm Gun M1. It remained in service until the end of the war in the Pacific.

It is unclear how the ammunition round ended at the border fence.
