fixed rib-fire animation glitch

- Added new armored vehicle for map maker: AAV-7A1, BTR-80 Desert/Woodland
- New enemy added: The Irregular Guard is a deadly elite unit loyal to Zakharov, the Ultranationalist leader fighting in the Russian Civil War. In the Nowheraki Ground Forces Pack addon, they replace the Warlord Bodyguard.

- Mountaineer rework - They are now divided into regular Mountainer and Mountainer Commando.
- Regular mountainers don't wear Armor anymore. Instead of wearing only the Chestrig, they travel faster and aim faster. In addition, the ratio of units using Rifle Grenade has increased significantly, and RPG-26 and Romat-MG have been obtained.
- Mountainer Commando is elite element of their unit. they are has a ROMAT-PARA Rifle that allows them to use Automatic fire mode. This weapon is the custom of Mountaineer unit. They also use grenades more actively.

- As a visual element, I added a wool collar to the model of Ultranationalist units. I'm not sure I can call it a visual element because it's hard to see at the top view.
- changed firing sound of AK-203 and AK-204.

- Increase Agressiveness of mountaineer
- Mountaineer assaulter now use mini uzi instead ppsh-41

- added ui for 2A42 Autocannon.

Balance :
- Enemies now usually can moving during shooting. Not if they are using general-purpose weapons, or are leader. Now they move seamlessly in CQB situations. also reduced the chances of enemies deciding to ambush. Therefore, they are more aggressive.
- General rifleman of NGF(replace Grunt Insurgent) will no longer wear body armor.
- The leader is now very likely to be ambush. He will protect himself for keeping provide buffs and orderto his troops. (hopefully)
- now mountaineers usually using rifle grenade launcher.

Fixed :
