The '''M1A1 Abrams''' is a tank used by the Hazardous Environment Combat Unit|HECU in ''Half-Life'' and its expansion ''Half-Life Blue Shift|Blue Shift''.

The encountered M1A1 Abrams tanks are always stationary, only rotating their turrets. They're typically found defending key areas that have been fortified by the HECU. Their primary attack method is explosive cannon fire, while some have attached Tripod-Mounted Heavy Machine Gun|Machine Guns.

In ''Half-Life'', the Abrams is first encountered in the chapter ''Surface Tension''. It provides fire support for a group of entrenched Marines. Another is stationed in the chapter ''"Forget About Freeman!"'', blocking the entrance to the Sector F|Black Mesa Central Complex. It has a mounted machine gun on its front.

A second unmanned tank is found in the same chapter in a vehicle repair bay. This tank has a Machine Gun mounted on its top which can be used to kill the enemies. In order to progress. Gordon Freeman|Gordon must climb into the tank's open hatch and activate the cannon to destroy the door blocking the path forward.

===''Half-Life Blue Shift''===
In ''Blue Shift'', an Abrams is encountered in the chapter ''Captive Freight''. It is placed on a train flatcar in the Freight Yard. Although it makes no use of it, this variant is armed with a TOW launcher, and is able to fully rotate its turret.

==Behind the scenes==
The M1A1 Abrams was created by Steve Theodore and is based on its WikipediaM1 Abrams|real world counterpart. The vehicle is built out out of brush-based entities. The source files for ''Half-Life''' maps reveal some unused variants. The map c3a1a includes two one in place of the active tank seen in the final game but facing the opposite direction, and another with a different and more detailed turret. In the next map, c3a1b, there was to be a second tank in place of the Energy Cannon.
