Militia vows to patrol border until wall is up

In the southeasternmost pocket of the US state of New Mexico, with El Paso, Texas, to the east and Mexico a stone's throw south, there is a small camp: a few tents and a weathered trailer. 

It is home to the half dozen or so members of the United Constitutional Patriots (UCP) -- a small but well-armed militia dipping their toes into the US border vigilante movement.

In recent months, thousands of migrants have arrived in Mexico, primarily Central Americans fleeing poverty and violence at home.

Based out of Flora Vista, New Mexico, the group -- made up mostly of older veterans -- enjoys an enthusiastic social media following. Striker can be heard fielding calls during lengthy radio broadcasts streamed online several times a week.
