* Mark time march is a stationary marching position where the feet are lifted and lowered alternately, but the soldier remains in place.
* Left flank march is a marching command that requires the unit to change direction to the left.
To execute a left flank march, the unit must first be in a marching position (moving forward) and then receive the command. Calling "left flank march" while at mark time would be confusing and ineffective, as the unit is not in motion to change direction.
To transition from mark time march to left flank march, you would need to:
1. Call "Forward march": This command brings the unit into motion.
2. Then call "Left flank march": This command will initiate the change of direction.
Let me know if you have any other questions about marching commands!
