Although there's the voice 'the command vehicle is taking damage', a lot of people have reported missing that. So perhaps the commander icon in the upper-left should flash red for a bit when the comm takes damage? Yes, it could be annoying, but the comm taking damage should be something that attracts attention... the voice-alert right now is too easy to miss, especially if someone is talking over it or another message preempts it.
Nice idea. White flashing might be more appropriate, as that's what happens when a building on the minimap takes damage, and it'd be slightly less distracting.
