We have used IR Strobes, "B_IRStrobe", spawned in from script and thrown, to designate targets for strike by the A164 Wipeout. The Wipeout is able to lock GBUs on these Strobes. Once the target is hit, the Strobe is destroyed. So far, so good.
Within 10-15 seconds of destroying the target - including the strobe - the pilot of the Wipeout is marked as a Teamkiller, with all the attendant issues to that status. {F23560}
