|align="center"|FileDm drill.png|64px
|While many soldiers learned to loathe Sgt. Sharp during advanced training, others are glad to know he's on the military's side. In active duty, Sgt. Sharp provides the soldiers an edge with his influence of discipline and morale.
|-
|align="center"|Hazardous Environment Combat Unit|Grunt Soldier
|align="center"|FileDm grunt.png|64px
|As the mainstay of the assault group, soldiers are trained and equipped with a huge variety of weaponry and combat tactics. The Grunt Soldier should make quick work of any civilian resistance.

|align="center"|FileDm recruit.png|64px

|align="center"|FileDm shephard.png|64px
|Separated from his group after his insertion craft went down, the Corporal wasn't able to join the assault on Black Mesa with the initial group. Shephard's experience in the facility, however, makes him pivotal in action against the resident resistance.

|align="center"|FileDm tower.png|64px
|Tower went in with Cpl. Shephard in the first wave. After his insertion craft was taken down, the attack group got separated and it was every man for himself. Tower's training enabled him to go ahead with his mission of rounding up the civilians.
