Can you prove your claim. cause, so far I know and as far as news goes, Bangladesh army has 128 BTR-82A on order, 144 BTR-80, 50 BTR-70, 88 MT-LB and 48 type-62 conversions. That gives you a total of 458 APCs.
Probably your figures are correct. But i remember discussing in this very forum about the number i stated. Was quite a while back. It could be wrong though.
