It has now been in use for 20+ years, and has had time to become a common plaything, with various accurate and not so accurate versions available. I posted the Supreme/SP Toys examples here a while ago, so lets look at some of the others...
Simply marked 'China' this hard topped troop carrier version is covered in markings, and looks like the sort of thing you'd find in a military parade somewhere in the Far-East. Next we have the Johnny Lightning/Playing Mantis open pick-up 'GS' version and was issued with a nice GMC pick-up in the same colour scheme. Another 'China' model finishes this row, an M966 TOW launcher.
These three are all by the same Chinese company, are much smaller than the others at around 1:87/1:90 scale, they are also quite crude models.
The bottom row starts with another Chinese model, a soft-topped GS, again covered in markings, most imaginary! Finally the two variations of the Hornby Railways Hummer as issued in the Battle Zone play-set. They are the only all-plastic ones in this line-up. [They are to be re-issued this year (2010) in the same play-set but with a new name; 'CODENAME STRIKEFORCE']
The figure used for scale, is a new Chinese piracy of recent Revell production, being a 30mm copy of a 23mm American soldier.
