* If you have any side mods installed please completely reinstall the game
* If you have 1.15.2RC4 installed follow these instructions, otherwise you will get "corrupted profile" error after game launch
* Install FIX5 patch only on EECH ver. 1.15.2, description at the bottom of page. It’s not included in 1.15.0 to 1.15.2 update.

- Tilt rotors of MV-22 are animated;
- New undercarriage animation mostly for all helicopters (except AH-64 and CH-3);
- New undercarriage animation system based on 3d scene sub-objects animation. To make it work like you want you just need to give proper names for undercarriage parts, make required animations for them and change values in suspension config file for this helicopter;
- Primitive suspension for AI controlled helicopters - wheels are align to ground surface, but if maximum or minimum limit of current gear is reached it doesn't works;
- Forest trees affected by fog;
- Specular glossiness for textured models;
- New detailed reflection images for different seasons;

- Additional campaigns - Cuba Libre, Cuba Libre 2, Border War (by ricnunes)
- US ATC voice pack (by LazerPotatoe)
- Troops insertion process optimized


- Additional type of collision points added – Stabilizer, Engine and Avionics. Cause corresponding damage;
- Additional points are added to helicopter objects;
- Position of collision points are calculating every frame, collision calculations of moving parts became more accurate;
- Collisions calculating precise increased – it's not cause false clashes, but works worse with very small objects;
- Collision of moving points (rotor blades) do not stop model but create dynamic force in opposite direction;
- Collision points of main rotors are moving automatically from damaged blade section to previous;

- Severity of Main rotor/Tail rotor/Stabilizer/Main rotor blade damage is decreased, Engine damage – increased;
- Value of damage repairing delay is different every time;
- Damage can be taken both from land and other object collision. Amount of damage is depends on current velocity and angle to the surface;
- Hard landing can't cause damage by itself (except undercarriage). If suspension will not able to reduce speed to zero it will be damaged and collision of fixed fuselage points will be calculated;
- Water random damage is added – than longer helicopter staying on water surface than more damage it gets (except CH-47 and CH-53). Engines will be damaged immediately in case of any engine collision with water;
- Repairing cheat has time delay when difficult is HARD;
- Alternative helicopter destruction. Instead of replacing whole model only weapons and pilots are became invisible;
- All aircrafts has armor level (look GWUT file);
- Damage states for aircrafts - mortal damage (30% of damage level left), critical damage (5% of damage level left), smoke appears. damage level decreased about 1 point per second if damage state is mortal, about 8 points per second if damage state is critical (only AI);
- Critical damage state for vehicles (15% of damage level left), vehicle became inactive, damage level decreased about 2 points per second, smoke appears;
- Smooth calculations of armor thickness after weapon impact (both vehicles and aircrafts);

Flight model

- Switchable weapon payload configs for helicopters with default cockpit;
- Dual-thrust rocket motors support, non-linear fuel consumption;
- All weapon types (include decoy, parachutes etc.) affected by wind;

did you leave checked "clear user profile" before installation? if so, did you manually copied playersv.bin from previous version after installation? look for playersv.bin and players2.bin file in cohokum folder, if there are any - delete them.
