Which of the following is a principle that should be avoided according to effective combat orders?

Qualified directives are discouraged in effective combat orders because they can lead to ambiguity and confusion among the troops. When orders are given, clarity and decisiveness are paramount for ensuring that all participants understand their roles and responsibilities without room for misinterpretation. Qualified directives typically involve hedging or making statements that include conditions or exceptions, which can create uncertainty during critical moments in combat situations.

In contrast, affirmative language, timely communication, and clear terminology are essential for effective combat orders as they promote understanding, quick action, and cohesion within the team. Effective orders should be direct and unambiguous to enable smooth execution of the plan.
