During my assignment to Colombia (1989 – 1995), I also worked with the Colombian military identifying guerrilla supply sources and supply lines. The picture above is of me conducting impromptu weapons identification training to a Colombian special forces unit in the Llanos in eastern Colombia during a mission to identify a captured cache of FARC guerrilla weapons and ordnance. The one below is of me with a Colombian patrol on watch on the road to Choachi, Colombia known as the Calera.
