The SIDAM 25 (Sistema Italiano Difesa Aerea Mobile 25) was an Italian SPAA produced by Otobreda and operated by the Italian Army. It entered into service in 1987 and kept serving with the Italian armed forces until the early 2000s. This vehicle was based on the M113 chassis with a new turret and gun system. The SIDAM 25 was armed with four 25 mm Oerlikon KBA cannons and a modern optronic system. In War Thunder, the SIDAM 25 is an anti-aircraft system capable of obliterating low-flying aircrafts thanks to the firepower of its four cannons. Sadly, it struggles against air targets beyond 2 km, and it is equipped with limited anti-tank capabilities.

The SIDAM 25 Mistral was an attempt by Otobreda to improve upon the SIDAM 25 by adding two Mistral surface-to-air missile pods to the platform, with the goal of increasing the maximum range of engagement against air targets. Despite this effective solution to a crippling problem, the new SIDAM 25 Mistral was not adopted by any military, not even the Italian Army, which was the main and only user of the SIDAM 25. In War Thunder, the SIDAM 25 Mistral finally becomes a capable SPAA, with the ability to hit targets several kilometers away, while still retaining its four powerful 25 mm Oerlikon KBA cannons to deal with foes who get too close.
