What must be recorded on a range card regarding the FPL?

Recording the magnetic azimuth in mils on a range card is essential for defining the final protective line (FPL) because it helps establish the direction in which the fire will be directed for optimal engagement of enemy forces. This information allows a unit to effectively coordinate and orient its weapons systems in relation to the threat. By specifying the azimuth, the team can ensure that all members are aware of the expected firing direction and can contribute to a unified defensive strategy.

Knowing the azimuth in mils aids in accurately plotting the FPL on the range card, which is a crucial tool for both planning and executing defense operations. It provides critical information that can be referred to during potential combat situations, allowing for efficient target acquisition and engagement.
