This writer’s biases about the Vietnam War (for instance; there’s a tiny section 2/3 through the book which mentions Australian and S Korean armor, and the larger section on PAVN armor at the very end mentions a breakthrough at Khe Sanh which he doesn’t mention in earlier accounts of armored engagement) mean I’m dubious of his “facts.” In short; this is a good visual guide to US and even PAVN materiel only, and a good pointer to other research, but essentially Americanized Dolchstoßlegende.
