Help ID a couple VN War subdued patches 1st LOG & USARV

[Survival]

Would like to ask for help to ID a couple Vietnam War subdued patches on a jungle jacket.  I know one is a Brigade patch but not sure which Brigade.  Don't know about the other one.  Many thanks in advance for your help.  The first one is actually pointing to the side rather then down as shown in the picture.

The round one is 1st Logistical Command, the other is USARV US Army Republic of Vietnam

USARV = US Army Vietnam

The black embroider onto OD twill patches were the forerunner to the fully embroidered green& black for the leaf camo uniform.  They were made only during 1966-67.  They were replaced because they just didn't hold up to the rigors of being on a combat uniform.  They're becoming their own field for collectors.

 

Hope this helps.

Airborne!
