Can a character give tactical advice from a mech that is shutdown?
No, unless,
What is he has a back-up military communicator?
Then possibly, but,
And what if the mech or unit in question is in such a position that they have no view whatsoever of the battle?
Now it's becoming tenuous.
We had a situation today where a mech was shutdown, facing away from all the action, and wanted to give tactical advice but I ruled that he could not on account that he had no information regarding the tactical situation. Though his argument was that in the heat of battle while attacking a heavier unit, he'd memorized what exactly was happening and that that information would still be relevant making his blind decisions valuable.
That's not a bad argument. I'd let him do it, but with a penalty to reflect his direct awareness. That penalty would dramatically increase each subsequent turn. The purpose of the the rules in question is that they only work if the leader can keep giving corrective/reactive advice. That he's able to respond to what's going on in the moment. The "memory" aspect would fade very quickly, and would only be relevant seconds out unless:
- Absolutely nothing changes in what the enemy does. 100% stationary force. No damage taken.
- Absolutely nothing changes in what the friendly forces do. 100% predictable (by the commander) moves. No damage taken.
IOW, that NEVER happens.
Also, note that the back up communicator would not have an easy time sending a signal out of a cockpit, so he'd be better off popping the hatch and sticking it out, at which point he might as well emerge as well to get his eyes on the action. Which might not help if his 'Mech is behind a hill. He might then have reason to dismount, walk up the hill and keep a low profile while offering advice. Depending on where he dropped compared to the action, that might not be risky, but I doubt it.
