I don't remember posting this...have you by any chance been editing that thread we were using as a "chatroom" earlier, Seventh? Yes
The riot shield barney is excellent, but one of the highlights is Ambient.Impact's excellent HGrunt. Actually, come to think of it, all of his models are of an excellent quality.

NOTE
Many of these models have transparent sections. These will only appear transparent if you:
A: Use Steam, since it has model transparency coded in
B: Download the transparency dlls from the HIT forums (http://hl-improvement.com). I think they're in one of the stickies in the model releases thread. Download them, and save them over the originals in C:SierraHalf-Life. DO NOT DO THIS IF YOU USE STEAM. It already has transparency, and the new dlls may stop it from working properly.
Also, if you want to see transparency in models without playing HL, download Jed's HL model viewer. It's an upgraded version of the normal HL model viewer from MilkShape 3D's website, and it supports transparency. You can also change it in the viewer like chrome effects, saving the job of editing the model's .qc file.
