One patrol leader is the commander of his submarines. His job is to navigate as many subs as he can through a mine field in a set amount of time - 5 minutes per patrol is a good starting point.
The opposing patrol leader sets up and manages his mine field to blow up the subs.

Lay out a start line and finish line with the minefield between the two. The 'Mine' patrol leader tells each mine where to stand in the minefield. Then, each mine puts on a blindfold. The patrol leader stands at the starting line to shout directions as needed.

All submarines stand at the starting line. Their patrol leader is at the finish line.
The first submarine puts on a blindfold and listens to his patrol leader's directions.

As the submarine is navigated through the mines, the 'Mine' patrol leader can tell specific mines to reach forward, back, left, or right to touch a sub. The mines can not move their feet.

When a sub is touched, it is destroyed, but the mine is still active. A destroyed sub removes his blindfold and leaves the game field.
