I noticed that there is no love for Allied indirect fire. The British only have the 6 pdr, and the Americans only have the 105. The Russians and Germans get their own heavy arty, going all the way up to the 152s. I've compiled a list of popular arty that definitely should be added.

Notes The 25 pounder answered the needs for a weapon that could be used as a field and a howitzer. The 18/25 pounder served as an interim weapon and many were lost when the BEF evacuated from France, leaving the army short on field artillery. The new version was introduced which combined a new box trail designed by Vickers which came with its own firing platform. This platform gave the gun a 360° traverse which was useful if firing at moving targets. The original barrels stayed the same at 87mm and the gun was called the 25 pounder Mk.2 on Mk.1 carriage. And this became to standard field piece found in both British and Commonwealth field regiments.

Traction Motorised (AEC Matador)
Notes The 5.5in gun was first introduced in 1941 and replaced the 4.5in as the standard medium gun. The 4.5in lacked the explosive power needed due to the low HE content of its shells. It shared the same carriage as the 4.5in Mk. II and a similar recoil system to the 6in howitzer. The gun was a complete success and it had a long career serving in British and Commonwealth medium artillery regiments.

Traction Motorised (Diamond T Truck or M5 Tractor)
Notes After developing a new carriage in which to mount their M1918 howitzers, the army decided to design a new howitzer instead of utilizing the older model, resulting in the M1 howitzer mounted on the M1 carriage. This same carriage was also used to mount the 4.5in gun which was to partner the new howitzer. The M1 had a longer barrel than the M1918 and had a new improved breech. The howitzer M1 was to replace the vintage M1918A3 which were still in stock, the M1 proved to be the best medium howitzer available to US forces not only in WW2 but in Korea and Vietnam. Along with the M2A1 105mm, formed the back bone of US Artillery Regiments

Notes Designed as a long ranged support weapon to partner its close relative the M1 155mm gun the M1 8in howitzer was also shelved only to be revived later. It was standardized in 1940 but priority went to the M2A1 gun. The first howitzers were produced in 1942 and were kept in production until 1945. The M1 was very accurate and first saw action in Italy in 1943. It was issued at Corps level to US army and the Marine Corps. After WW2 It was redesignated as the M115 howitzer and continued in service through the Korea war and Vietnam.
