ModdingQuestion - 'Untargetable'

[ColonelSheppard]

How to make a unit with a mod 'untargetable' for a few ticks/seconds and the targetable again?

[worstinfinland]

I think that if one could make a new unit 'type' that would be called "untargeteable" like submerged but wouldn't be targeteable by torpedos (submerged unit on land/air anyone?).

[ColonelSheppard]

Commander, means land and water but it's trival if torpedos still it, the important thing is that engines can no longer repair it and current repairing or any other kind of engine support is imediatelly aborted
