This photo shows Mexican Marines (According to MP.net) using a M2 mounted on a RAM truck. Presumably they are on an anti-narco mission.
Up until 2009, Chrysler was mostly owned by Cerberus Capital Management, the same company that owns The Freedom Group which owns Remington Defense, Bushmaster et. al. It seems to me that they missed out on product cross pollination opportunity. Chrysler could have offered lightly armored RAM trucks, with mounted Remington Defense manufactured machine guns, to developing countries who are fond of such things in lieu of real LAVs (light armored vehicles).
