Help with identifying a general in this photograph

[Desiree]

Hey folks, update on this intriguing photo from the family archives at a "Society of the Golden Sword" event (VFMAC's donor society, est. 1975). My dad, Lt. Col. Jean Kossarides (far right, shades and drink in hand), is there: WWII P-47, P-51 pilot, Korea test flyer (MiG shrapnel, Purple Heart, DFC), CIA whispers, NASA ties. 
 

The Facebook group ID'd the the gentleman second to the left as Brig. Gen. (Ret.) Theodore C. Mataxis, a Cold War warrior who served in WWII, Korea, Vietnam, and aided Afghan Mujahideen against Soviets, son of Greek immigrants, just like Dad's roots! All of a sudden I was like yes I remember that name! 

I have been unable to ID the gentleman on the far left. I believe the gentleman next to my father was head of the CIA at the time, but I don’t remember his name.
 

Can anybody identify those two in individuals? I’m new here and I have apologize if I’ve posted this in the wrong group, but I searched and I didn’t know where else to post this.

Its the officer on the far left end that's Mataxis, not the one next to him, Theodore C. Mataxis Sr

 

There was a Mataxis Junior

 

Here in South Vietnam 1971, Senior does the honors for Junior of pinning his new rank on his coat,  Senior was Assistant Divisional Commander Americal Division then, photo taken in February of that year, 1st Lieutenant Theodore Mataxis JR to Captain, I gather Mataxis the younger is also in the Americal, I believe this was Mataxis the youngers second tour of duty.

I never would’ve guessed that! It looks like two different people from the photo. 🙂
