Final answer:
The terms command by negation, command by substitution, command by exception, and command by addition are not commonly associated with mortar operations in military science. Mortar commands are direct and precise given the nature of the operations.
Step-by-step explanation:
The concepts such as command by negation, command by substitution, command by exception, and command by addition are not typical terminology used in the field of direct fire support like mortars. Instead, these terms more commonly relate to management and organizational leadership styles. In military science, particularly when referring to mortar teams, command is usually structured through clear, direct orders, chain of command principles, and standing operating procedures.
Mortar commands are typically direct and precise, given the critical need for accuracy and the potential consequences of mistakes. Command by negation, which means only intervening when there is a deviation from expected performance, and command by addition, which implies adding commands to the existing set, are not commonly associated with mortar operations where direct orders and real-time adjustments are vital for mission success. In the context of mortar fire, commands must be concise, clear, and followed immediately, leaving little room for the nuanced approaches implied by these terms.
