|Inner Sphere Military Ranks|
|For specific ranks see Military Ranks|
The rank of Sergeant Major is frequently the highest enlisted rank a soldier can reach in their time in the military. Usually the Sergeant Major is the highest ranking non-commissioned officer in a battalion, and is responsible for the discipline and conduct of all enlisted personnel in the battalion.
 Lyran Commonwealth and Lyran Alliance
 Draconis Combine Mustered Soldiery
In the DCMS and DCA, a sergeant major is known by the Japanese title Sho-ko. Their rank insignia is a royal blue katakana 2 on a colored background appropriate to their branch of service. Frequently they are the second in command of a lance or platoon. In the DCMS Support Corps (Technical Service), the equivalent rank is known as Chief Petty Officer. They wear the Sho-ko's rank insignia.

 Armed Forces of the Federated Suns
In the AFFS, the Sergeant Major is the highest rank possible for a soldier to reach without attending a military academy. Typically each battalion of a regiment has a Sergeant Major who acts as the liaison between the officers and enlisted men.
In multi-regiment formations (like a Regimental Combat Team) one Sergeant Major is typically given the rank of Command Sergeant Major and is responsible for all the enlisted soldiers and non-commissioned officers in the unit.
Unlike many Inner Sphere militaries, the AFFS Navy doesn't use a distinct rank for its enlisted and non-commissioned officers. They are instead known by the same rank regardless of their service branch.

 Capellan Confederation Armed Forces
In the CCAF, these soldiers are known as yi-si-ben-bing thanks to the reforms enacted by Sun-Tzu Liao as part of his Xin Sheng movement. Though translated as Master Sergeant, the duties and obligations of this rank make it more akin to the AFFS Sergeant Major or SLDF Master Sergeant rank than than the DCMS Master Sergeant rank, which is mostly honorary.

 Free Worlds League
In the FWLM, each regiment has a single Sergeant Major. This person is responsible for the conduct and discipline of every enlisted solider and NCO in the regiment. As it is the highest enlisted rank in the FWLM, soldiers who hold this rank are accorded a great deal of respect by their fellows. This rank is known as Master Chief Petty Officer in the FWLM Navy, with one MCPO per WarShip, JumpShip, and DropShip.
Prior to the Andurien Secession in 3030 and the passage of the Military Reorganization Act of 3046, the Duchy of Andurien's Defenders of Andurien regiments also used the rank of Banner and Master Banner in place of Sergeant Major.
To indicate their rank, FWLM Sergeant Majors and Master Chief Petty Officers use three gold chevrons on a purple background with a black bar and circular tab above it.
 The Clans
The Clans in general do not use enlisted ranks. The nearest equivalent used by most Clans is the Point 1-5 system used by conventional infantry platoons or WarShip crews. A Point 5 could be considered a high ranking Sergeant, but is probably not equivalent to a Sergeant Major.
 Clan Star Adder
Clan Star Adder is unique among the Clans in that they have a position called Adder Keeper, which could be considered a Sergeant Major or Command Sergeant Major. This warrior advises the Star Adder Khan and saKhan about matters related to the non-Bloodnamed warriors of the Star Adder Touman. Only warriors who haven't earned a Bloodname are eligible for this position.
 ComStar/Word of Blake
This rank isn't used in the ComGuards or Word of Blake Militia. Instead a senior Acolyte or an Adept would be assigned these duties. ComStar Acolytes use a ComStar logo with a gray halo to show their rank, while an Adept's insignia uses a blue halo. Word of Blake Acolytes use a brass medallion; Adepts use a medallion made from silver. Insignia shows theta symbol, indicating JumpShip/WarShip crew. Other service branches replace theta with appropriate Greek letter.

 Free Rasalhague Republic
In the KungsArmé this rank is known by its Swedish name, Fanjunkare. To show their rank, a Fanjunkare wears a blue patch with an orange tau cross on it. The spaces below the arms of the cross are filled with orange rectangles.
 Periphery Powers
 Magistracy of Canopus
In the Magistracy Armed Forces, the senior NCO of a battalion is known as a Command Sergeant. Their regimental level counterpart is known as a Banner Sergeant. The rank draws its name from the tradition of entrusting a regiment's colors to a highly experienced soldier. The modern MAF Banner Sergeant still performs this duty on formal occasions.
A Command Sergeant wears a single silver diamond to show their rank, while a Banner Sergeant wears two silver diamonds set above each other.
 Taurian Defense Force
In the TDF a battalion's senior NCO is called Battalion Chief Sergeant. A MechWarrior on active duty in the TDF holds this rank, but has no additional command authority. The equivalent in the TDF Navy is Air Chief, who commands a flight of two AeroSpace Fighter lances. The Battalion Chief Sergeant wears a Lance Sergeant's rank insignia, but adds a red dot in the center.
 Marian Hegemony
The Legiones Marianes, with their focus on re-creating the Roman Empire, do not use this rank. The nearest rank in their military structure is miles gregarius. A set of two inverted silver chevrons make up the rank insignia of a miles gregarius.
 Outworlds Alliance
Sergeant Major isn't one of the eight ranks used by the Alliance Military Corps. The AMC identifies its battalion senior NCO as a Preceptor. Their rank insignia is worn on each lapel, and consists of two green circles next to each other with brown dots in the center of each circle.
