The raw recruits, those volunteering for duty and those drafted on their 16th birthdays, begin military life as Privates (PRV).  The symbol of their rank is called the Narrow Arrow (or, sometimes, the Blunt Point), represented by an arrow with a single black line dividing it.  Privates through the rank of sergeant wear their insignia on the shoulder of the uniform.  Narrow Arrows and other types of insignia stitched to uniforms are usually Steiner Blue against a black rectangle.  the colors are reversed for dress uniforms.
After about one to six months, the young soldier is promoted to Private First Class (PFC).  This signifies a degree of practical experience as well as the completion of any advanced training.  The symbol of this rank is called a Half Hunter's Point.
The next rank up, and the beginning of a soldier's introduction to leadership, is Corporal (CP).  The symbol is the full Hunter's Point, the razor-edge tip of the arrow that bow-hunters sometimes use in big game hunts.
The next advance in position is to the rank of Senior Corporal (SCP).  With it comes increased responsibilities and the beginning of intensive leadership training under the tutelage of a veteran Sergeant (SG) who tries to teach the critical importance of quick reactions.  The insignia of Senior Corporal is the Hunter's Point with a black triangle in its center.
The six grades of Sergeant (SG) form the backbone of McCarron's Armored Calvary.  These are the noncommissioned officers, experienced in leading men and fighting battles.  The unsung heroes of war, Sergeants are the glue that binds troops together and they also serve as the crucial link between officers and the common grunt.  Academy trained Mechwarriors usually start their career as Sergeants. The rank symbol of Sergeant is the Hunter's Point with a single black circle in its center.
The next rank up is the Staff Sergeant (SSG).  Staff Sergeants typically have at least five years' experience in the military.  As a sign of his rank, he wears what is known as the Spear Point.  A large, downward-pointing triangle, it contains two other triangles, one fitting inside the other.  Both smaller triangles share a common edge along the upper side of the insignia.  Staff Sergeant officers up through Hauptmann-Kommandant rank wear their insignia on the upper arms of their uniform and a blue stripe down the outside of their trouser pants leg.
The next rank up, a Sergeant Major (SGM), is the highest NCO normally found on the battlefield.  Sergeant Majors form the bulk of instructors in MAC boot camps and oversee the first few weeks of training in many academies.  The Sergeant Major wears a short horizontal bar added above his Spear Point insignia.
The Staff Sergeant Major's (SSGM) Spear Point has two horizontal bars added above his Spear Point.  The Staff Sergeant Majors are battalion NCOs and usually have administrative rather than combative duties.  They are charged with ensuring the smooth running of the battalion, maintaining both order and morale.  They also serve as a conduit between the officers and enlisted troops, being respected by both groups for their experience.
Senior Sergeant Major (SenSGM) is the highest rank a noncommissioned officer can achieve in McCarron's Armored Calvary.  Most have at least 20 years of service with the military and are entitled to wear service braids on their dress uniform.  There is usually one Senior Sergeant Major per regiment, and his responsibility is to ensure the discipline and well-being of all recruits and other noncommissioned officers.  His rank insignia is known as the  Spear Point, and shows his special importance.  This insignia is similar to the Staff Sergeant Major's, with two horizontal bars added above the spear point.  It also includes an additional gold triangle across its center.
The grade of Leutnant (LT) is slightly different in MAC than in other militaries.  A MAC Leutnant has not yet won a commission, and is therefore not formally an officer.  The rank provides a testing period, particularly in 'Mech units, during which the soldier's leadership and technical skills are judged. 

Leutnants are often addressed according to their job ('MechWarrior, 'Pilot', Gunner', for example) instead of their rank.  Many will remain at this level for the rest of their careers.  The more ambitious or capable Leutnants are soon given temporary command of a lance or platoon to further test their leadership skills.  The Leutnant wears a spear point similar to that of a Staff Sergeant, but with the smallest triangle blackened.
If the soldier shows the necessary leadership and tactical skills, he is then promoted to First Leutnant (LT1).  First Leutnants receive a commission in the MAC plus a permanent command of a lance or equivalent combat unit.  The rise in rank is shown by a single horizontal blue bar above the Leutnant's spear point patch.
A Hauptmann (HPT), or Captain, as they are sometimes known to the public, is the commander of a company.  He is the last officer that will consistently see battle on a day-to-day basis.  As a result, he is accorded the greatest respect by enlisted and non-com officers.  His insignia is similar to the First Leutnant's, except both interior triangles are blackened to show his increased importance.
Kommandants (KM) are usually chosen from among battalion commanders for their mental skills in such areas as tactics or logistics.  They are accomplished tacticians and administrators, often with at least a decade of service in the military.  The grade is represented by a Hauptmann's spear point with a single horizontal bar above it.
The rank of Hauptmann-Kommandant (HPT-KM) is usually reserved for the senior battalion commander in a regiment.  This rank has no equivalent in other militaries.  This officer's responsibilities are to ensure that the regiment fully understands the orders of his Colonel and that the Colonel and his staff are fully aware of the situation on the battlefield.  Furthermore, they serve as an information conduit between the junior officers and the colonel, ensuring that the regimental commander has the information needed to make decisions.  The Hauptmann-Kommandant wears an all-black spear point on his sleeves.  This is the last rank that uses a sleeve insignia.
Leutnant-Colonel (LT-COL) is the lowest rank among senior officers.  As a regiment's second-in-command, he is in charge of the information-gathering as well as ensuring that the regiment is properly supplied and equipped.  If the battle is particularly difficult, the Leutnant-Colonel will sometimes be given the command of certain crucial regimental units, freeing the colonel to oversee the entire engagement.  The insignia of the Leutnant-Colonel is a single silver pip, an elongated diamond-shaped piece of metal worn on the collar of field uniforms.
As commander of McCarron's Armored Calvary the Colonel (Col) is to be sure that the unit is well prepared and any contracts with employers are understood by all.
