They probably forgot to clean the barrel; look at how dirty the tank is.There is a claim that a Thai VT-4 tank, while firing against the Cambodian side, suffered a burst barrel and exploded, injuring 3 crew members.
But if it were the barrel itself, it shouldn't look like this. It seems more likely to be a breech failure, ammunition malfunction, user error, or a hit from an anti-tank missile.
What are your thoughts?
