Sub Command sports three training missions, 23 single missions, and one 14 mission campaign. The campaign can be played from either the Russian or US side, so in effect there are two campaigns. The single missions range from search and rescue, battle group escort, tailing enemy boomers, spy missions, and general-purpose search-and-destroy. Many missions strictly prohibit firing on the enemy as you are expected to mirror real life Cold War objectives and get in—get out without being seen. Some missions offer you more than one choice of township submarine--you may play the mission as the Akula, 688(I), or the Seawolf.
