SIDAM 25
Contents
Description
The Sistema Italiano Difesa Aerea Mobile, 25mm (shortened to SIDAM 25) is a Rank VI Italian self-propelled anti-aircraft gun
with a battle rating of 8.3 (AB/RB/SB). It was introduced in Update 1.85 "Supersonic".
The SIDAM 25 is an optronics-aimed SPAA equipped with 4x25mm Oerlikon KBA Cannons with the ability to fire HEI-T* and APDS. Because of the high fire density, this SPAA is able to destroy planes withing seconds and just needing a few rounds to hit their target. The M792 and Default belt rounds (HEI-T*) contain a TNT equivalent of 54.4 grams in each of the projectiles, and have a high muzzle velocity of 1100 m/s, making target leading much easier. However, because of the the lack of armour defeating rounds in the standard belts, your maximum penetration remains 3 mm until you get the M791 belt (APDS). Once the M791 belt is unlocked, defeating tanks will be much easier, given the 110 mm of penetration at 10 meters, and a muzzle velocity of 1345 m/s. The potential is however severely limited by the maximum capacity of 60 rounds (15 per gun). Overall, be very careful with your ammunition considering the firerate and the small ammunition count. 4 x 550 rpm and a maximum of 660 rounds means you have about 18 seconds of continous fire available.

Sensors
The SIDAM 25 is equipped with a 3JB10 optronic tracking system, with no search radar. The tracking system does not trigger the radar warning receiver fitted to some helicopters.
|
Although the tracker can track targets in an elevation range of -20°/+85° once locked on, it can only initially lock on to targets between -20°/+20° in elevation. |

Usage in the battles
Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons
Pros:
- Has an Optronic tracking system allowing targets to be tracked and providing a lead indicator
- Optronic system cannot be detected by radar trackers on enemy helicopters, making it much easier for you to target them
- 550 RPM on the 25 mm guns, a combined 2200 RPM
- Two-axis stabilizer which is very stable
- Incredibly quick turret traverse and gun elevation
- APDS can penetrate 110 mm, plenty to defend against enemy vehicles (once it is unlocked)
Cons:
- Thin armor, can be hull-broken
- Relatively poor zoom/magnification, harder to spot small targets at range (especially scout helicopters)
- APDS rounds are a tier 3 modification - until then, anti-armour work is not possible given the low penetration of the HE rounds
- Not very mobile compared to other tanks and SPAA at its rank
- Only 60 rounds per APDS belt (15 rounds per gun)
- No search radar - only optronic targeting, meaning you need to have a visible target to lock on, and a clear line-of-sight to track it
- Can only lock-on to targets -20°/+20° in elevation
History
Describe the history of the creation and combat usage of the vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === Encyclopedia Info ===, also if applicable).
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
