As a general practice, when I see any empty triangle I immediately target it. When TAGed, the empty triangle becomes visible to anyone on your team not affected by ECM (assuming you, as the TAGer, are not under effects of ECM) -- even if they have no line of sight to the target. Hopefully, someone somewhere will target that sucker and unload LRM death on them, but it still can't hurt to target them yourself to see what their mech is packing.
