If player tank under the command of AI-commander (another tank) and you squad have a repair-specialist or engineer (in cargo), then after damage your vehicle there is no way to call it. This scheme works perfectly with infantry and medic when a player reports about wound and then the AI commander sends you a medic. In the case of vehicles, the player can not report any damage-status , please add call-support also to vehicles. This will be fair

I know that AI-squad leader ( in which squad your damaged vehicle is located ) can independently order a repair specialist to repair damaged vehicle in his squad, but this is not stable. Sometimes there are no repair orders while
the repair-specialists are present in the squad.

In those moments, the status "I am damaged" is very desirable. Devs Please add this command!
