Thailand is now actually in a rush!
After pass order to Ukrain,Thailand only gets 20 units of T84 6 years later!
With the 20 Units T-84 from Ukrain (berely made it, they have civil war issue),and with the more 28 units VT-4(already deliveried)+21 units(under production),Thailand has now 69 New 3rd generation MBT, this si some number but not that much really.
Vietnam has 1,500 tanks (although most of them are old models), but Vietnam continues to introduce more relatively advanced T90s. Both China and Thailand should be wary of the increase in Vietnam's tank power. However, the Vietnamese army(tank power) pose more threat to Thailand, Laos and Cambodia than that to China.
