US army leadership - Essay Example Perhaps, it is these values, principles, and system that make the soldier have the respect that is accorded him everywhere he goes. ‘An army of principles can penetrate where an army of soldiers cannot’. The implementation of the structures however depends largely on the functions of personnel in the army. The military institution is made up several officers whose duties are to ensure that there is orderliness with within the rank of soldiers put under his control and that the structures and systems are well implemented. One of such indispensable figures in the implementation of military structures is the non-commissioned officer. The non-commissioned officer however does not work untamed: for the non-commissioned officer to succeed in his role as a leader, he needs to be guided by basic military principles. This is to say that the non-commissioned officer cannot rule within his own discretion but needs to be guided by principles such as the application of the FM 6-22, c ounseling and the seven Army Values. Roles of Non-Commissioned Officers Who is a non-commissioned officer? A non-commissioned officer is a military officer who is given authority through a commissioned officer, but he or she is not technically considered to be in command. Non-commissioned officers rise up through the enlisted ranks, generally with several years of experience to their names before they reach positions of nominal power.The rank an officer has to reach to be accorded the position of a non-commissioned officer varies from country to country and from military force to military force. Also among the ranks, there divisions such as Junior NCOs and Senior NCOs depending on which nation is in question and which military force, be it the Navy, Army or Air Force.

And that means we must focus on the basics, maintain Army values and facilitate the transformation’ (Anthony, 2001). Even though all roles performed by non-commissioned officers are geared towards enhancing administratio n in the army force, there are varying roles and these roles cut across different areas of operation; defining who may be under the orders or authority of the non-commissioned officer and who may not. In a generalized system however, the role of a particular NCO depends on his rank. The FM 7-22.7 makes a list of five (5) major categories of non-commissioned officers and what their roles are. These categories are classified according to ranks of officers and they are Sergeant Major of the Army, Command Sergeant Major and Sergeant Major, First Sergeant and Master Sergeant, Platoon Sergeant and Sergeant First Class, and Squad, Section and Team Leaders.
