I was with the 298th Signal in Quang Tri `70-`71. We did comm for the Northern District.Set up all the firebase comms.I worked with many Marine units,
Not familiar the term VMFA,but guessing Viet Nam Marine Force ?.
VMFA means Fixed Wing(V) Marine(M) Fighter(F) Attack(A) aircraft. In my case it was squadron VMFA-232 the “RED DEVILS”. F4J Phantoms. Danang. Electronic Countermeasures Tech. (ECM).
