Final answer:
The reference material does not provide an exact number for the required weekly spot checks by the XO/LCPO. It only indicates an increase in annual drill requirements for the Army. Without official military documentation, an accurate response is not possible.
Step-by-step explanation:
The question pertains to the minimum number of spot checks that must be completed per week by the Executive Officer (XO) or Leading Chief Petty Officer (LCPO). The provided reference material does not specify the exact number of spot checks required.
It discusses changes in the annual drill requirements for the Army, indicating an intention to increase from two weeks per year to up to seven weeks per year.
This information, while it provides some context about the increased operational tempo and duty requirements for reservists, does not give a direct answer to the question about spot checks.
Therefore, without specific guidelines from official military protocols or standing orders that detail the number of required spot checks, it is not possible to provide an accurate response to this question.
