H-93: Exterior Walls

Previous: H-90: Ballistic Reduction

H-93. For exterior walls, the use of a BFV or artillery piece in the direct fire role is ideal if the structure will support it and if the ROE will allow it. The BFV’s 25-mm cannon is a reduction weapon when using HE rounds and firing a spiral firing pattern. (See figure H-13.) The main gun of an M1-series Abrams tank is effective when using the HEAT round. However, the APDS-T round rarely produces the desired effect because of its penetrating power.
