This is a player model that fits especially well when you're underarmed and rushing towards an enemy... It works very well in-game and comes from a customized grunt for Half-Life, found on this website: http://www.hl-improvement.com/forums/index.php?topic=3519.0
To install, extract the MDL and BMP files into your directory here: ...\Steam\SteamApps\Your@E-mail.com\Half-Life\valve\models\player\comrade\ (and make note of the new folder)
Downloading this will also let you correctly see other people who use this player model. For the Common Good!
