In Black Mesa, there are three 'public' services, that everyone who works there know about. These are the scientists, the security force and administration. Unbeknownst to practically all of them, is the fourth service, know as the Hazardous Enviorment Tactical and Retrieval Unit, or HET-RU. The people who work in HET-RU are only known by the administrator and vice administrator, the Chief of Security, the few of scientists who have reached high enough security clearance to use them and the people unfourtunate enough to encounter them. HET-RU is Black Mesa's version of the US military's HECU or UK military's SAS but these guys fight in much tougher situations.
The actual missions these guys are sent to include retrieval of Unknown material from other galaxies, universes or dimensions, stopping alien overloads from obliterating said galaxies, universes or dimensions and so on. My name is Jack Alamatry, and I am 3rd specialist soldier of HET-RU. This is our part in the Black Mesa incident, Gordon isn't the only hero in this.
