Mortars
When I first saw these I started looking for the ammo which the launch, sadly I did not find where they kept the ammo. They probably were not allowed to have it there.
Some of these are really huge and they even showed us how they adjust the pipe to hit the target. They had a mini war for us later on in the day, no live rounds were fired but they did show us how they use mortars in this mini war.
It must be great to see a little about the artifacts they use in wars and to give some explanations of how they are used and the precautions to have! What great pictures
