Syria, as you may remember, was a French "mandate" before WWII. Local forces there, plus French forces stationed there were of course equipped with French weapons, including armored vehicles. When the French left, the new Syrian government inherited all the equipment left behind. When the state of Israel was established, Syria and other Arab countries immediately invaded. One Syrian tank, which was a pre-war French light tank, was destroyed in an attack and it sits there today, right where it was destroyed.
Likewise, the French (again) in Indochina had much American equipment, including M24 (I think it was) light tanks. A TV program featured some French army veteran describing his last action there. He was a tank crewman on an M24 (I think it was), which was knocked out by the VC. He returned to Vietnam (this I think within the last ten years) to find his old tank, sitting where it was destroyed.
Near where I live, over the river in Maryland actually, there was a Civil War period or slightly later gun emplacement on the banks of the Potomac River upriver from Ft. Washinton. The original gun, a huge muzzleloader, was still there when I visited it about 35 years ago, half buried in the dirt. However, it's probably gone by now. Not a tank but a virtual graveyard just the same.
