BI, please pity the ears of the player:
Sometimes, the Tank commander (the AI) is not able to finish his voice command.
And then the voice command is stuck and the AI-commander repeats the same thing, an infinite number of times.
The only way to end this is to kill your own commander or close the game.
As seems to me, this bug is can be connected with the interaction of the two commands - "Repair comand" and "Get In command". If the squad of AI tank commander has a such units as - Repair specialist or Engineer, then the commander will order them to repair the damaged tank. In the some cases, for unknown reasons the Repair Specialist or Engineer can't make repair of this tank or even to this moment can be even killed, but the commander won't stop your request and order to the other units get in the damaged vehicle. We know, that the AI won't sit in a damaged vehicle, but the commander continues his voice command.
BI, as seem to me, you need to configure the interaction of two AI commands - //Repair// and //Get in//.
