Mortar Glossary
A complete, browsable reference of mortar fire direction terminology — mission types, methods of fire, sheaf patterns, and FDC vocabulary — organized for quick lookup in the field or the classroom.
Random Data Generator
Generates a second gun data set from your selected base point — deflection wraps 0–6400 mils, elevation clamps 0–1500 mils — with a mil change that matches the selected drill.
Mortar Tables Checklist
Blank MTO (Message to Observer) table for recording target number, weapon system, rounds and type, max ord, TOF, azimuth, range, fuse setting, and angle T. One landscape page with a filled-in example row.
Built for the mortar community
The Mortar Bible was built for the mortar community, by mortarmen and for mortarmen. It is a living reference and not a doctrinal publication, so it should always be used alongside current field manuals, firing tables, and your unit's SOPs.
