(adsbygoogle = window.adsbygoogle || []).push({}); You've most likely been killed by someone in the armoured kuruma, but it has one big weakness.
If you find a kuruma vacant just kick all the doors off, 5 or so kicks and the whole door comes off, repeat with all four and that kuruma has armor no more.
The boot and bonnet can be kicked off as well.
Or you could just blow them up.
