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 stock and are very fast, easy to hit long-range targets as well as fast moving ones
• Has access to gen 1 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
• 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

History

ItO 90M (IlmatorjuntaOhjus 90M) is a French-Finnish self-propelled SAM system, using CrotaleNG MOD VT-1 Crotale missile system fitted into Patria XA-181 6x6 chassis. ItO 90M is the modernized variant of the ItO 90. Finland has produced 21 of these launch vehicles during 2007-2010.

Guidance and Firepower

The Crotale NG system fires the VT-1 medium range surface to air missile that can reach speeds up to Mach 3.5. It is deemed effective against both helicopters and fast moving jet aircraft. The maximum horizontal range is 11 km and maximum altitude is 6 km. A single missile can be launched and guided at a time. Interval between engagements is reported as short.

The Crotale VT-1 is guided using radio commands from the launch vehicle. The missile is tracked by the launch vehicle by either fire control radar or infrared camera. The ItO 90 is fitted with a 30 km range tracking radar, TV camera and infrared camera. The 20 km search radar allows for independent operatiom. However, it is most effective in a coordinated role with inputs from longer range early warning radar. The ItO 90M improvement allows for optical fire direction away from the vehicle, increasing crew survivability. Possibly it also allows for fully passive operation of the launch vehicle, not using the radar.

Protection

The ItO 90 is based on the XA-181 chassis, which is a derivative of the XA-180 armored personnel carrier. The steel armor protects the crew from small arms fire and shell splinters. The ItO 90M allows for fire direction away from the vehicle, increasing crew survivability. When used in a passive mode the ItO 90 is less effective, but also better protected from anti-radiation missiles.

Mobility

The XA-181 wheeled chassis allows for good mobility on roads and reasonable cross country mobility. Since the ItO 90 is much heavier and has a higher center of gravity the off road mobility is reduced compared to the regular APC variants. The ItO 90 is not intended to be used while on the move. Three outriggers provide stability in the firing position.
