|CK-27 carbine rifle|
The trooper is a class of terran light infantry.
The trooper is the backbone of the Defenders of Man militia. They are similar to the standard terran marine, but do not wear the CMC Powered Combat Suits that marines usually do. Troopers are armed with CK-27 carbine rifles.
The trooper appears in the missions "The Escape" and "Enemy Intelligence." In terms of stats they are identical to the marine, with the same damage and range, same HP, and same movement speed. However, they cannot use stimpacks and lack the marine's combat shield upgrade.
