All potential squad members are classed by their set of abilities. The list of classes is as follows:
| Icon | Title | Description |
|---|---|---|
| Assault | Assault troops are powerful, mobile soldiers used for closer and short-range combat. They also provide good defense. | |
 |
Heavy | Heavy troops provide more firepower and can therefore deliver more damage. They carry LMGs and Rocket Launchers. Though their weapons pack a good punch, they have limited reloads. |
 |
Sniper | Sniper troops are chiefly used for long range, targeted assaults and reconnaissance duties. |
| Support | Support troops are multi-purpose units used in a variety of roles, including scouting, as field medics, sentries and other support roles. | |
| Psionic | Psionic troops only become available later in the game, once troops have been tested for the ability. They can influence the enemy telepathically through panic and can sometimes control them. |
