This might help but, my concern is that army recognition site doesn't list Vietnam having such as the
BTR-60PB/70 I'm providing that site as well.
Concerning the
BTR-60PB there might be some "
wiggle room" there based on how they described the Country User (
CU) section as saying "Currently, the
BTR-60PB is in service with the Russian army and
many countries over the world."

As opposed to this for the
BTR-70 as referred to by one of the first two refs of them having also. From the
CU section in alpha order
"
Country users
Afghanistan, Azerbaijan, Bangladesh, Belarus, Estonia, Georgia, Hungary, Kazakhstan, Kyrgyzstan, Lithuania, Mali, Macedonia, Moldovia, Nepal, Pakistan, Romania, Russia, Tajikistan, Turkmenistan, Ukraine, Uzbekistan."

The
FIRST TWO refs.

https://totalmilitaryinsight.com/vie...rmy-equipment/
As noted above.

(Click on Left to access the other equipment categories. The listings seem to have a good amount of information and a listing of in the TANK section of Cold War era ones as well if it is felt any might be worth revisiting.)
Yesterday we were given the
GIFT of receiving our 1st Great Grand in this daughter!!
That was the
BEST news of the day after finding out when I got to work a very good friend of mine from passed away the same day. He was a co-worker and
30-year veteran of the USMC.
When very young my
grandmother 
once on the way to mass after hearing similar news said something along the lines of "Sometimes the Lord takes one (Life) to give one (Life)".
