Well, Spock, I personally love modeling the weapons and equipment of the Israeli-Egyptian, Syrian, and Jordanian conflicts. Lots of modified vehicles on both sides of that conflict.
If you are interested in the African wars, Google searches are going to net you a lot of results. However, South Africa makes a huge number of armored vehicles and artillery pieces and scatters them all over the world. I have yet to see more than a couple of kits of any of their equipment though. I would like to try and scratch build some of their artillery pieces someday though.
Give it a look, maybe something will peak your interest. For goodness sake, there is so much variety in the armored world that there is no reason to get bored. Just look elsewhere around the globe!
