It's another commonality here: UN Trucks.
These trucks belong to UN Peacekeepers (UNIFIL) in the south. The trucks in my photo are here in Beirut because those folks need some R&R now and then, so they come to town. I walked past these trucks parked outside a West-Beirut hotel.
A few times in early evening, I've seen massive convoys of a different sort of UNIFIL trucks. These convoys include tanks, APCs, and heavy machinery. It's impressive, their parades of dozens of enormous trucks etc., and I've often wondered if that's part of some sort of planned rotation.
