The coast guard uses them in a few areas of the country. mostly high profile stations that get SAR or a lot of public affairs cases. I believe station Miami might have a few. Having said that I would NOT paint it with USCG markings as they will be kind enough to take it from you for impersonation a federal asset. A guy painted a Robinson R44 with uscg markings and even saved a life with it. The USCG was not impressed and he was fined and lost his helo.
They may no longer use them. Last I heard they did but that was in 08 before I got out.
Does the USCG even count as military??!!!
It would have been cool to see a olive drab waverunner with a M60 on the bow though,....
