Notes: This is the newest self-propelled howitzer to enter British service, growing out of the GBT-155 program in early 1980s. In 1989, it began replacing all other self-propelled artillery in the British Army. Production stopped in 1995, but after a few months, was resumed. It is in a class with the M-109A6 Paladin, PZH-2000, and Slammer, using a 52-caliber gun barrel, inertial navigation system, GPS, and fire control and solution computer. (Most British Army vehicles use a 39-caliber barrel, with about 20% using a 45-caliber barrel and 10% using a 52-caliber barrel. Most Kuwaiti vehicles have a 52-caliber barrel.) The AS-90 can stop and begin a barrage within 15 seconds (3 phases) if the target's location is known. There is a driver’s hatch on the front left deck, and two hatches on the turret deck for the commander and loader. In the rear of the turret is a large door for resupply and crew entry. This vehicle is in service with the British Army, and a small amount have been sold to the Kuwaitis.

Notes: This British-built SP howitzer was developed in the late 1960s, and was for a long time the standard vehicle of its type in the British Army. They were mostly phased out of British service when the AS-90 Braveheart became available, and most of the Abbots were sold off to India or several African nations, but some were kept in reserve or for training purposes. The Abbot is based on a stretched FV-432 APC chassis, topped with a large turret mounting the howitzer. It is amphibious with about 5 minutes of preparation. There is a hatch on the front left deck for the driver, and two hatches on the turret deck for the commander and crew, as well as a door in the rear of the hull for resupply and crew entry.

Twilight 2000 Notes: These vehicles were reactivated in the Twilight War. Some 20 examples were also kept in Canada by the British Army for use in training, and some of them saw service with the Canadian Army against the Russians or Quebecois.
