AR 190-5 (Motor Vehicle Traffic Supervision) para 2-7 covers when GOMORs will be issued for DUI offenses.
If the Soldier refused a Breathalyzer then paragraph 2-7a(2) applies. If they tested over .08 or violated the local state law for DUI then para 2-7a(3) dictates a GOMOR. The reason I state this is some states, you can have less than .08 but get a DUI if you were pulled over for speeding, weaving, or any other traffic infraction and you had any amount of alcohol detected by a Breathalyzer.
So, even though the Soldier was not cited by local police for DUI, the Soldier may still be in line for a GOMOR.
