Syria
Syria has around 4,500 tanks and 4,510 armored personnel carriers. Syria also has about 180,000 soldiers. Please be mindful that these are pre civil war statistics, and that Syria could very well, and most likely has significantly less forces than these, and the only way we will know for sure, is when hostilities in Syria are over.
If Assad stays in power after the war, he will probably order in more tanks from Russia.
