This is a Matchbox Rumble Raider.
http://en.wikipedia.org/wiki/Marauder_%28vehicle%29 It appears to be based on a real vehicle in service with several countries.
It's not an exact match, but it's pretty good.
I got a few of them to use as auxiliary vehicles.
They are a nice big model.
Shown here with Esci 1/72nd scale Warsaw Pact infantry.
