The SIDAM 25 is an Italian anti-air platform developed by OTO Melara during the Cold War. Based on the M113A1 platform, the SIDAM 25 was primarily designed to fulfill the short-range air defense needs of the Italian army. The Italian army initially showed interest in the OTOMATIC anti-air platform; however, due to factors such as cost, the SIDAM 25 was chosen instead. One of its main drawbacks was that it lacked a radar system unlike other anti-air platforms of the era. A total of 275 systems were ordered. In the late 2010s, the SIDAM 25 began to be phased out, with most units being used to arm the Freccia IFV with a 25 mm cannon.

Introduced in Update 1.85 "Supersonic", the SIDAM 25 is equipped with 4 x 25 mm Oerlikon KBA cannons able to fire both HEI-T* and APDS rounds. The high fire density of this SPAA allows it to destroy planes within seconds, often requiring only a few hits to bring down the target. The HEI-T rounds in the M792 belt contain a TNT equivalent of 54.4 grams in each projectile, with a high muzzle velocity of 1,100 m/s, making it easier to lead targets. However, the standard belts lack armour-penetrating rounds, so your maximum penetration remains at 3 mm until you unlock the M791 belt (APDS). Once the M791 belt is unlocked, defeating tanks becomes much easier, thanks to the 81 mm of penetration at 10 metres and a muzzle velocity of 1,345 m/s. The potential of the platform is however severely limited by the maximum capacity of 660 rounds (165 per gun). It is important to be very careful with your ammunition considering the fire rate and the small ammunition capacity, giving approximately 18 seconds of continuous fire. However, once your rounds hit their target, there is little that can survive. Helicopters and aircraft will be brought down with ease if you remain undetected. The platform's mobility is just sufficient to reach desired positions, but its large size makes it difficult to go unnoticed on the battlefield. The SIDAM 25 also lacks sufficient armour protection, as heavy machine guns can easily penetrate it. In conclusion, stay hidden and fire only when you see an opportunity to do so.
