Notes: Though this vehicle was officially named the Sherman Fire Support Vehicle, the name "Priest" was given to it by British crews who looked at its pulpit-like commander’s station. Based on the chassis of the M-4 Sherman series, the M-7 has no turret, an open top, and mounts a 105mm howitzer instead of more normal Sherman armament. The Priest was, like the Sherman, widely exported, but by 2000, remained in service only by Yugoslavia, Israel (in a reserve role), and some South American and Southeast Asian countries.

Notes: This elderly self-propelled howitzer dates from US use in the early 1950s. It went out of US service in 1962, but during the Twilight War was still being used by Greece, Jordan, Spain, and Taiwan. Turkey also used them, but these were upgraded in the 1980s to the M-44T standard (see Turkish Self-Propelled Artillery). The 155mm L/30 gun has much shorter range than normal NATO standard 155mm howitzers (see Howitzers, under Large-Caliber Guns), but can fire all 155mm rounds. The fighting compartment is open-topped, and there is a cupola for a machinegun. A door in the rear allows for resupply.

Notes: These ancient self-propelled howitzers were still being used by Greece, South Korea, and Spain at the turn of the century. Turkey upgraded their M-52s to the M-52T standard in the late 1980s and early 1990s (see Turkish Self-Propelled Artillery). The M-52 uses the shorter-range 105mm howitzer, and the turret has large doors in the rear for ammunition resupply. There are two hatches on the turret roof for the commander and gunner, and the commander's hatch has a machinegun mount. The driver is in the front hull on the left.

Notes: This self-propelled howitzer was developed in the 1950s at the same time as the M-110 203mm SP howitzer. It has been long phased out of service in most armies that once used them, including the US, but in 2000 was still being used by Greece, Iran, Israel, South Korea, and Turkey. The vehicle is normally accompanied by a drove of M-548 tracked load carriers or M-992 FAASvs, carrying the ammunition and 8 members of the gun crew. The chassis is the same as used on the M-110A2, but like the rest of the vehicle, the gun hasn’t been produced since 1980, and parts for it are getting hard to find by 2000 except in countries actively using them. The gun is carried on top of the chassis of the vehicle. This gives no protection to the crew from small arms fire or artillery splinters; to remedy this, a tubular framework was issued with the vehicle that could be erected around the firing position; over which Kevlar shields are placed. Most of the time, these were considered too cumbersome and difficult to use, and they were typically left strapped to the side of the vehicle or abandoned in the rear areas. Without these shields, the turret armor value from all directions is 0.

Notes: This elderly self-propelled howitzer is still being used by Brazil, Spain, Taiwan, and Turkey. The driver has a hatch on the front left deck, the commander and gunner have hatches on the turret roof, and there are large doors on either side of the turret and in the rear of the turret for ammunition loading. The vehicle is not NBC protected. It is amphibious with preparation (takes 3 minutes) through inflatable bags that attach to the hull above the tracks.

Notes: The M-109A2 self-propelled howitzer was designed on the same chassis as the M-108 SP howitzer, and also shares most of the turret components. The M-109, however, uses a 155mm howitzer, and the M-109 far outlasted the M-108, still being produced until today in several countries and used by over 25, with a bewildering array of modifications and refits, as well as different barrel lengths for increasing range. The M-109 has a hatch on the front left deck for the driver, and there are two hatches on the turret deck for the commander and gunner, with a weapon mount in front of the commander’s hatch. There is a large door in either side of the turret, as well as a double door in the rear of the turret for ammunition loading. The M-109 is amphibious, with preparation; floats must be attached to each roadwheel and several more to the hull; this takes 15 minutes.

Notes: This is a significant upgrade of the M-109A2/A3. Delivery of these vehicles was completed by October 1998.

The new cannon has an advanced bore evacuator, a new breech housing, and longer length that allows for longer range. The armor on the turret is improved and has Kevlar ballistic lining; a new fire control system is fitted, with GPS, onboard fire control computers, inertial navigation system, and automatic fire control input; frequency-hopping radios, night vision gear, a 5kW generator, a water heater (for heating rations), and a reduction in crew required to four. The Paladin is capable of laying and firing the howitzer without input from the FDC if the target’s location is known, via the Automatic Fire-Control System (AFCS). The Paladin may decrease reload time to 1 for one minute.

Externally, the Paladin is distinguishable by its large bustle on the turret rear and the longer gun barrel.

Notes: This self-propelled howitzer quickly replaced the earlier M-110 and M-110A1, both of which used the far shorter-barreled and ranged L/25 guns. The M-110A2 uses the same chassis as the M-107, and at the time of the Twilight War was still being used in small numbers by the US and in larger numbers in 13 other countries. As there is almost no room for ammunition on the vehicle, and also no room for 8 of the crew members, the M-110A2 is normally followed by a large amount of support vehicles carrying these members and the ammunition, such as the M-548, M-648, or FAASV. The gun is carried on top of the chassis of the vehicle. This gives no protection to the crew from small arms fire or artillery splinters; to remedy this, a tubular framework was issued with the vehicle that could be erected around the firing position; over which Kevlar shields are placed. Most of the time, these were considered too cumbersome and difficult to use, and they were typically left strapped to the side of the vehicle or abandoned in the rear areas. Without these shields, the turret armor value from all directions is 0.
