General info
Survivability and armour
With only 8 mm thickness of armour overall, the ItO 90M can be penetrated by even rifle-calibre machine guns from any direction and any hit from HE shells, artillery strike, autocannons and air attacks must be avoided. Thankfully, ItO has relatively long hull and the crew is spread out at the very ends of front and rear of the vehicle, so it's unlikely to get one-shot by enemy kinetic shells from sides. Besides, ItO don't have any reserve ammo rack, and there are only engine and fuel tanks at the middle of hull, so sometimes it will absorb many rounds from inexperienced enemy. The unmanned turret is quite vulnerable to overpressure damage due to its exposed and volatile ammo, yet it will become a competent bullet magnet once run out of ammo. Sometimes it could even sustain several hits of 9K127 Vikhr from Ka-50 and Ka-52.
Armour type:
- Rolled homogeneous armour (Hull, Vents)
- Bulletproof glass (Windows)
- Structural steel (Tracking Radar, Lifting Legs)
| Armour | Front (Slope angle) | Sides | Rear | Roof |
|---|---|---|---|---|
| Hull | 8 mm (40° - 60°) Upper Glacis 8 mm (0° - 60°) Lower Glacis 60 mm (40°) Windows 5 mm (58°) Lifting Legs |
8 mm (0° - 17°) Top 8 mm (20° - 23°) Bottom 5 mm Vents |

8 mm 5 mm Vents |
| Turret | 8 mm Turret 15 mm Tracking Radar |
8 mm | 8 mm | 8 mm |
Notes:
- Wheels are 10 mm thick
Mobility
The ItO's mobility on paved roads is overall satisfactory. It has acceptable acceleration on plain terrain which can reach around ~45 km/h at average. However, ItO's poor power-to-weight ratio results in bad off-roading capability which limits its performance on hilly terrain maps. Sometimes, it can't even climb slightly sloped mound without full modifications. As a wheeled vehicle, ItO also struggles on soft ground and narrow streets. Its reverse speed is mild and will cause some problems when you're fighting against helicopters behind covers. To sum up, ItO has acceptable mobility on certain terrains, but you need to choose your path wisely so you can swiftly hide into covers without stuck by terrain when you are found.

Armaments
Main armament
The main armament of the ItO 90M are the VT1 SACLOS-guided surface-to-air missiles. It's an outstanding aircraft killer which has a peak speed of around Mach 3.7 and 35G of maximum overload. These features give VT1 capability to catch high-speed jet fighters even when they are maneuvering. At the same time, 8 m of trigger radius and formidable 7.86 kg of TNT equivalent also secure the hit rate and the destruction of target. With capability to launch 8 missiles in few seconds without reloading, you can wipe out several nearby air targets swiftly before they find you and fight back.
ItO 90M has 2 missile launchers amounted bilaterally at its unmanned turret. Each launcher can fire 4 rounds of VT1 but can only reload in captured points due to absense of reserve ammo racks. These launchers are also quite spread out, and first 4 shots will launch from the left one. Sometimes, the cover will accidentally block your missile and alert the enemy aircraft of your location.
Although ItO 90M can't launch on a move, it's not uncommon that you have to guide VT1 to intercept Vikhr before evading into cover. Hence suspension and brake modifications might help in supposed situation.

Usage in battles
When you spawn, it is advised to use your speed to drive to an area near the edges of the map and try and pick off any helicopters and unaware aircraft. Try to use foliage as cover and attempt to stay as hidden as possible. Your goal is not to get hit.
Use your missile range to your advantage and try your best not to be spotted.
Pros and cons
Pros:
- One of the longest ranges in the game at a maximum range of 12 km
- VT1 missiles come with the stock vehicle and are very fast, they can easily hit long-range targets as well as fast-moving ones
- Has access to gen 3 gunner thermals
- Can fire all 8 missiles without reloading
- Good vertical range of elevation
Cons:
- 8 mm of all-around armour is insufficient to stop even .50 cal machine guns below 1,000 m
- The search radar, when unfolded, sticks out quite far giving it a very tall profile - can however be folded
- Lacks any sort of self-defence against ground targets
- Lacks any sort of mobility uphill - and without mobility upgrades, the vehicle is nearly immobile due to the immense overweight on a 6x6 wheeled chassis
- The tracking radar is inoperable when the search radar is turned off
History
The ItO 90M is based on the Sisu XA-180 platform and uses the French surface-to-air missile systen called CrotaleNG MOD.[1]
In 1980, Sisu produced an XA-180 prototype for testing. It competed against two other prototypes, but was the winner of the trials in 1983. in December 1983, the Finnish Army ordered a first batch of 50 XA-180s, of which 9 were reserved for UN. The vehicle proved itself successful and more were ordered by the army.[2]
