The HECU finally decide to forget about Freeman and cut their losses by retreating from the facility and launching airstrikes throughout the facility, leaving behind only a number of 'last chance' soldiers that are still determined to take him down with them.Īfter the HECU failed to kill Gordon Freeman, it seems a large remnants of the soldiers were left behind, and were soon facing a new threat, the Black Operatives were deployed in silencing the incident themselves when the soldiers failed to contain the Resonance Cascade incident, and are openly hostile towards the HECU, either by interrogating them or killing them on sight. But with all of this combined in their ultimate anti-Gordon effort he still managed to prevail, taking down everything and everyone in the way of his goal to stop the invasion. The HECU were thereby reluctant in stopping Gordon from escaping the facility, using whatever means they could to stop him including, tanks, helicopters, and heavy explosives. With this knowledge in hand the HECU were convinced that Gordon had sabotaged the spectrometer and caused the rift purposely, making him their main target in the operation. It was there that the spectrometer failed disastrously and was destroyed, thereby opening the inter-dimensional rift between Earth and Xen, officially marking the start of the Black Mesa incident. Gordon Freeman was working as a research associate at the Black Mesa Research Facility, where he was working in the anti-mass spectrometer in the Anomalous Research laboratories of Sector C. The HECU entered armed with helicopters, tanks, artillery, and more than enough ammo to take on the alien forces as best they could, often remaining in a stalemate between the two that would eventually be broken by Freeman. It was there that the soldiers got their orders to cover-up the situation, meaning kill all the aliens, and the scientists, and especially, Gordon Freeman. However the HECU were not told what their mission was when they headed out, it was believed to be nothing more than another baby-sitting job by soldiers, but as the soldiers entered the uncontrollable chaos that was the Black Mesa incident they knew it was anything but.

The HECUs biggest (and last) mission was to take care of the Black Mesa incident, a large 'Inter-dimensional rift' leaking hostile aliens throughout the Black Mesa Research Facility in New Mexico. HECU soldiers tend to be heavy-handed, being eager to kill anything that moves and going out of their way to kill it, often getting upset because it's not challenging enough. HECU personnel consists of squad leaders, grunts, medics, engineers, and snipers, dressed in black and white camouflage fatigues, and a Powered Combat Vest, with several miscellaneous items such as ammo pouch belts, gas masks, balaclavas, and night vision goggles.

Thereby making them better qualified than regular soldiers for hazardous situations, however this usually only amounts to a couple baby-sitting jobs. The HECU is a special operations division of the United States Marines, consisting of specially picked soldiers who are trained and readied to operate in harsh environments that include things such as:
