In all seriousness how should we be doing things?
1. Train men to shoot. This was the failing of Train Fire -- men shot under "combat conditions" before they mastered the basics (the "combat conditions" weren't very realistic, either.)
2. Train men who have mastered the basics to shoot under combat conditions. We now do a very good job of this, using unit firing, combat theaters, and so on.
(Note -- this is how the Marines did it. They never adopted Train Fire, and were always better shots than the Army.)
3. Manage replacement fill for the convenience of the tactical commanders, not for the personnel managers.
a. Do not keep all units at the same percentage of fill. Allow units to fall BELOW average fill, then pull them off line, fill them with a draft of replacements.
b. Move replacements directly to their combat units -- don't waste time elsewhere.
c. Assign replacements to experienced combat NCOs or senior men. Stress to the old timers that the new guys are their responsibility.
d. Base all training on the unit officers and NCOs, and on the unit's actual missions.
e. Conduct combat operations in a relatively safe area before returning the unit to full combat duties.
4. Stress multi-echelon traning. Don't neglect the NCOs and Officers.
5. Develop leader training to remedy deficiencies that show up in the field and to keep leaders abrest of changing situations, enemy tactics, and so on.
6. Thoroughly analyze enemy actions, and base combat training scenarios on actual enemy actions.
7. Conduct detailed rehearsals before major combat -- at the least, conduct "rock drills" for leaders.
