The Bearcat Armored Truck Series followed Lenco's successful Bear Armored Truck Series, which was used by many American Law Enforcement agencies. The name Bearcat is actually an acronym for Ballistic Engineered Armored Response Counter-Attack Truck. The smaller Bearcat was designed to perform duties the larger Bear vehicles were not able to accomplish.  Based on a upgraded Ford F550 Super-Duty truck chassis, the first variant, the Bearcat G2, was so successful it resulted in a modified Military variant and spawned a number of upgraded versions in both Law Enforcement and Military versions.  Advertised duties that the Bearcat family can perform are Ambulance/Medical Evacuation, Anti-Riot Protection, Armored Personnel Carrier, Assault/Counter-Assault, Convoy Protection, Emergency Response/Rescue, Explosive Ordnance Disposal, Gun Truck, Patrol, Perimeter Security, Reconnaissance, Route Clearance and VIP Transport.

Bearcat Military Variants consist of the G2, G3, G4 MATV, G5, EOD, MedEvac and VIP.  Additional variants are the Tactical SUV, which is marketed as a Law Enforcement Vehicle and Anti-Riot vehicle, marketed to the "International" community.  Some basic facts and identifying features of the Military Bearcat variants are as follows:
