Recent imagery of the Latin American-based special operations competition organized by U.S. South Command has shown that some members of the Panamanian contingent were using 5.56x45mm IWI X95 select-fire carbines during the small arms live fire portion of the course. In particular, there were only two Commandos of the Panamanian team that were pictured with the X95s with a tan FDE finish. The other team members ran through the carbine portions with 5.56x45mm NATO M4 carbines as they had been doing every year. However for the competitors running the X95s, it appears they actually came from a different branch of service than the M4 wielding teammates, due to the uniforms (Multicam versus digital) and gear they were donning.
From the Defense Media Activity-
Panama is one of the few countries in the world that doesn’t have a military but instead a self-defense force and in particular a border force that has seen action with the FARC rebel group on the border with Colombia. Known as the SENAFRONT, this border security group has been pictured with IWI X95s in a black finish since at least April of 2015 when images appeared on the group’s Twitter page indicating the presence of the carbine with them. However, upon inspection of some of the photographs, it appears that the Commandos using the X95s have a unit insignia unlike any of the battalions in SENAFRONT.
