Final answer:
The term for soldiers needing additional instruction or practice in a particular skill is 'training'. Training encompasses learning military rules, discipline, and teamwork, with a focus on readiness and adherence to military standards.
Step-by-step explanation:
For soldiers who have demonstrated that they need and would benefit from additional instruction or practice in a particular skill, the correct term would be training. This is because training specifically refers to the process where members of the military learn new rules, bond, and follow structured schedules set by their leaders to achieve team unity and operational effectiveness. Skills such as keeping their areas clean for inspection, learning to march in correct formations, and saluting when in the presence of superiors are all encompassed within military training. Furthermore, learning discipline and the capacity for hard work are fundamental aspects of soldiers' training which enable them to set aside personal goals to accomplish missions and, after service, transition to civilian life with valuable skills.
Military training ensures that soldiers are ready to effectively carry out their duties and adhere to the discipline that is required in military life. This systematic approach to developing soldier skills is essential for maintaining the high standards expected within the armed forces.
