"North", "South", "East", "West", "Surface in sector C", "Fire torpedo at B6", "Lay mine", "Detonate mine at E5", "Activate Drone – are you in sector B?", "Activate Sonar", "Silent running".

Special rules for Real-Time Battle:

During a "Surface maneuver", draw a circle around one submarine compartment on the Engineer’s map and write initials inside the circle.

• Charges systems by crossing off one box each time there is movement.
• Announces when a system is ready.

Examples:

"Charging torpedo, mine, silent running, drone, sonar"
"Torpedo, mine, silent running, drone, sonar ready"
