Military Police....
I was on active duty in the MPs, Military Police(what is now 31B).
We were taught to ask for
both the service member's state issued DL & the DoD/2A ID card.
This was during traffic stops that involved government issued motor vehicles.
And
yes even
active duty troops can have active warrants or commit crimes.
Do you think a civilian sworn LE officer doing a traffic stop on a service member just looks at a DL, then says; "okay, go ahead" .
Service members on active duty can commit crimes then same way private citizens can. Murder, armed robbery, car theft, rape, aggravated assault, etc.
The US Disciplinary Barracks at Fort Leavenworth KS are filled with convicted killers, rapists, robbers, child molesters, etc.
