1) //If the driver is alone(gunner was killed), and he sees the enemyin the danger mode, he can take the position of the gunner, after this he can again return to the position of the driver.//
2) //If the driver is alone(gunner was killed), and he sees the enemy, he can just periodically to leave the driver's seat and fire the primary weapons, after this, periodicallyafter this (aware mode) he can again return to the position of the driver.//
32) //If the driver is alone(gunner was killed), and in the danger mode, and he seeshe can just to leave the driver's seat and fire the enemyprimary weapons, then he can just leave the vehicle and will return back only just when he get back to Aonly after this (aware mode.), (Not danger mode)//he can again return to the position of the driver.//
//PS: Any game is made up of little things. For this reason details should not be left unattended. Little things - is what builds great things... Let's do Arma is better//
