Hotfix: Fixed the issue with AI defense tanks leaving their positions. Fixed the issue with krasnopol not being able to be guided to attack the ground.

热更新：修复了AI防御坦克离开阵地的问题。修复了krasnopol 无法被引导攻击地面的问题

新机制：
1、现在在征服模式敌人的防御点内会随机的有防守的坦克，坦克随着时间推移会越来越先进。
2、新增2K25 “红土地”制导炮弹

该炮弹发射前，需要玩家使用激光指示器持续照射目标。激光指示器由专门的班组携带。玩家也可以在GRU的spotter和2S3M的储物空间内找到。


新单位：M109A5、2S1。
错误修正：
1、修复了某些车辆在修复后，乘员反复下车的问题。
2、修复了敌人AI使用如标枪类的导弹时候，导弹不会追踪目标的问题（此项需要再验证，不过应该不会影响单人游戏体验）

优化：

优化了车辆对目标的弹种选择。现在车辆不会使用atgm攻击掩体后的士兵。

New Mechanics:
1. Now in the conquest mode, there will be random defensive tanks in the enemy's defense points, and the tanks will become more and more advanced over time.
2. Added 2K25 "krasnopol" guided artillery shells
Before firing this shell, the player needs to use a laser designator to continuously illuminate the target. The laser designator is carried by a special team. Players can also find it in the storage space of the GRU spotter and 2S3M.
New units: M109A5, 2S1.
Bug Fixes:
1. Fixed the problem that the crew repeatedly got off the vehicle after repairing some vehicles.
2. Fixed the problem that the enemy AI would not track the target when using missiles such as javelins (this item needs to be verified again, but it should not affect the single-player experience)
Optimization:
Optimized the vehicle's choice of target shells. Now the vehicle will not use atgm to attack soldiers behind the bunker.

Improved tank targeting.
Changed equipment for 82nd Airborne.
Changed units for 82nd Airborne doctrine in skirmishes.
