His summation of TET 68 is partially correct, but how they failed wasn't detailed.
They may have 'intended' to stay in the cities. But, I do remember my unit (199th Light Inf) going into the center of Saigon to the Cholon district and kicking their behinds out of their entrenched HQ in the Phu Tho racetrack and over the next 3 months playing hopscotch chasing their remnants all the way over the Cambodian border at Tay Ninh.
The Gyrenes did the same at Hue up north kicking asz and sending them packing back over the border in pieces.
Thanks for your service and for sharing this with us and your realities of what happen post TET.
ASA Vet has been telling for over a decade that you guys did not lose TET battle.
You are correct as it was US INF Division units, Special Forces Mike Force types plus South Koreans who kicked the VC out of cities. My unit just off the Ban Me Thout East airfield went into BMT and kicked as-. The ARVN 23rd Division was between us and downtown. They were a sorry ass unit. All the men I served with who had been there in TET had a bad taste for the ARVN plus the LLDB on SF A Teams and above. LLDB meant Lousy Little Dirty Bast-—s to SF.
