Laser Squad, a further development of Rebelstar, might be one of the first tactical combat games published.
The player takes a squad of 5 to 8 soldiers into combat while trying to accomplish the mission.
The player would have to chose the equipment for each soldier before starting the mission.
There each member of the squad had different values of skills, and action points that were expended for the different actions taken.
This was the predecessor of the better known X-Com, from the same author.
