Peacekeeper
Cadillac-Gage 'Ranger'

This vehicle, best known to the US Air Force as the PEACEKEEPER, was a five-ton (4535.9 kg) lightly-armored truck, using a late 1970s-model Dodge pickup chassis, and originally powered by a 360 cu.in. (approx. 5.9 liter) V-8 engine.
In 1976, the US Air Force requested a vehicle that could provide enhanced protection for USAF Security Police personnel tasked with guarding its highest-priority assets: alert bombers, vital weapon storage areas, and remote ICBM sites such as Minuteman II Launch Facilities. After USAF prototype acceptance, the contract was awarded in 1979, and the Air Force received delivery of the first of over 570 of these vehicles beginning in March of 1980. Strategic Air Command bases were the first to receive these vehicles. Among them, Ellsworth Air Force Base's 44th Strategic Missile Wing, the parent organization for these Delta sites, was among the first base to put Peacekeepers to work.
In this missile field, the 44th Missile Security Squadron (44 MSS) safeguarded each of the Wing's 15 Launch Control Facilities (LCFs) like Delta-01, while its partner unit, the 45th Missile Security Squadron (45 MSS), provided maintenance escort, area response coverage, convoy escort, and site-specific security for the 150 Launch Facilities (LFs), like Delta-09. The 45 MSS was the exclusive user of Peacekeepers in this missile field, staffing them with heavily-armed four-person crews known as Fire Teams, the basic ground-combat element in the U.S. military at the time. A Fire Team consisted of enlisted Security Police personnel, the ranking member being their Fire Team Leader (M16 rifle), a Gunner (M60 machine gun), a Grenadier (M16 rifle with attached M203 (40mm) grenade launcher), and an Assistant Gunner (M16 rifle) who helped the Gunner and carried extra ammunition and equipment.
Peacekeeper vehicles were durably constructed and had an intimidating profile, especially whenever the Gunner stood in the hatch behind his pintle-mounted M60. They performed their assigned roles satisfactorily, but they did have their shortcomings. The vehicles were not designed for comfort, and that became evident on every back road and on every hot or cold day. Their engines and tires were troublesome. The vehicles were notoriously top-heavy, which led to several roll-overs and injuries in the field. They had extremely limited visibility, which rain or winter weather only worsened. Lastly, they were awkward to board, ride in for lengthy periods, or to deploy from, each issue producing its own minor injuries. But for all their warts, these armored warriors did what they were designed to do. They helped USAF Security Policemen to safeguard the Minuteman missile system, and they provided a measure of added safety for the troops who risked their lives daily to help uphold America's deterrent readiness.
Peacekeepers served here from March 1980 through the inactivation of the 44th Missile Wing on 4 July 1994.
A number of restored Peacekeepers--most of them veterans of hard duty in American ICBM fields continue to soldier-on as SWAT or bomb disposal team transports for a few civilian law enforcement agencies today.
