Kinda what Pete said.....and, if you have that on your vehicle while performing your "role"....dontcha think that might clue in the bad guys??
I don't know how much they stick to "roll" now-a-days, but it would be kinda a give-away.
If you have another vehicle, talk to the SWCies and maybe have them fabricate an "auxiliary" tag for you that you can use on your non role vehicle.
Just a thought and my .002 worth.
Thanks for helping and supporting training our great troops too.
