How many steps does the fourth squad take when given the command "Open Ranks, March"?

When the command "Open Ranks, March" is given, the fourth squad, which is typically the last squad in a formation, remains in place—this is referred to as "Stands Fast." The action of the fourth squad not moving helps maintain alignment within the formation as the other squads move forward to create the necessary space between them.

The first squad moves forward two 30-inch steps, the second squad moves forward one 30-inch step, and the third squad also moves forward one 30-inch step. The fourth squad's standing fast allows for proper spacing and order, ensuring that the formation opens up correctly. This coordinated movement showcases the precision and discipline required in military formations and drills.
