Negative unless you count riding in them. I was 12C5P Armor/Cav Officer in CP Casey, Korea and Ft Stewart, GA. Got out in '90, came back in as a 19D, did a tour in Bosnia with 1-104 CAV PAARNG and then transitioned to 31D and went to Iraq with 31st MP's from FT Campbell. Waiting on My Warrent packet.
