- fixed ghillie suit's empty icon

- The Force Recon ghillie suit is no longer just a decoration. It can now be equipped in the Support Gear (Big slot). When worn, Recon marines gain the ability to disguise themselves.
- The disguise animation for Forward Observers has been updated. Additionally, their movement speed is now reduced while disguised.
- Combat Engineers can no longer use the M14 EBR. This restriction does not apply to Attachment Riflemen.

improved flaregun animation

fixed localization issue

- fixed wrong localization about Mk.21 Grenade
- changed animation of stacked Mk.21 Grenades

- Army rifles and USMC's Doctrine tree are expanding so they getting a lack of Doctrine points more than I intended. So I've removed or integrated some doctrines.
- The animation of build sandbags position has been changed.
- USMC Gunner can use Rifle instead of M240. If gunners are using Rifle, boost nearby gunner who using the M240. Because trooper carry spare ammo together, mobility doesn't increase significantly.

- improve compatiblity with IOV

- now USMC rifles can use M18 Pistol.
