The PBR was 1st used by the Navy to patrol the inland rivers and coastlines of South Vietnam. This boat proved to be very effective in its use.
Countless records speak for theirselves.
E-Mail Jimmy here. Below are two photos of PBRs in South Vietnam. It really did not have a authorized unit patch even. As it was attached to the 18th MP Brigade, the MP patch was modified and was claimed as a unauthorized patch. Being a Bastard unit was not all bad, mostly you were left alone by rear echelon nitwits.
