The M3A1 Halftrack was modeled by Agus and Rad and skinned by Agus.
The M3 Halftrack origins date back to 1938 with the M3 scout car, which was designed by the White company. It was later decided to add tracks to the rear of the vehicle, creating the M2 Halftrack. This M2 was too small to be used as a personnel carrier and so it served as an artillery tractor and reconnaissance vehicle. In 1940 the M3 Halftrack appeared. It was much bigger than the M2 and it had room for as many as 13 people (3 in the front cabin and 10 in the back). In total, nearly 41,000 M3 Halftracks were produced in the war. They continued to be used long after the war ended, with as many as 22 countries still using them in the 1980s.
The M1 Mortar was modeled by altfuture and Toddel and skinned by Toddel.
The M1 Mortar was a slightly improved version of the Brandt mortar, which in turn was based on the Stokes Trench Mortar, used by the US Army in World War 1. It could fire up to 18 rounds per minute at a maximum distance of 3 kilometres. It could be split up into three parts (the barrel, the base and the bipod) of roughly 20 kilograms each. This allowed it to be quickly moved and deployed, giving the US infantry battalion a lot of firepower and flexibility.
