Section VII. MORTARS

5-31. GENERAL

    The FSO should plan and control mortar fires to ensure they are integrated into the overall fire plan. Mortars are very effective against lightly protected personnel and for obscuration, illumination, and close-in defensive fires.

Mortars:

    Clearance of fires, including mortars, must be addressed in the commander's guidance and maneuver rehearsal process.
