A briefing given before a mission begins is divided into two parts - the first, focuses on the background of the mission and where it takes place, and the second, using the mission's map, details the objectives the commandos must complete, any important information they need to know, and what they must use to escape the area.

In the game, the player assumes the role of an allied officer, who has been entrusted to command a group of commandos on each of the game's twenty missions that they undertake.
