The Vietnam War myth

[FM WarB]

Here is an interesting article about the fall of South Vietnam in 1975.

I have seen the figure of 600 for NVA tanks in the campaign. Would anyone have more specific numbers for NVA and ARVN armored forces in 1975?
Not counting 1445 PZI, the Germans had 1223 PzII, 202 35T, 78 38T, 98 PzIII and 211 PzIV (Jenz, Panzer Truppen, vol 1) for a total of 1612. So it seems the Germans had more tanks for the invasion of Poland than the NVA did in 1975.
Just doing a little fact checking, and note the "house of cards" reference in the recommended article.
