This formula is customarily simplified to the following:
(Task) (statement of the assigned task),
(Purpose) in order to assist in the successful execution of (statement of the superior's general plan).
The words "assist in the successful execution of" may frequently be understood and therefore omitted.
The mission, thus formulated, clearly indicates the appropriate effect desired, i.e., the factor which establishes the basis for the solution of the problem from the standpoint of suitability.
B. Relative Fighting Strength.
As indicated in the Fundamental Military Principle, the second and third requirements for a sound solution of the problem are feasibility of accomplishment and acceptability of the consequences as to costs.
Both requirements have to do with the factors of relative fighting strength. Fighting strength is derived from the means available as influenced by the characteristics of the theater. Relative fighting strength is determined by a weighing of these factors against the means opposed, as influenced also by the characteristics of the theater.
These are the factors, then, which are next studied in the Estimate. They are studied in order to complete the establishment of the basis for the solution of the problem.
