Lieutenant Colonel

A Lieutenant Colonel is usually the executive officer of a regiment of ground troops or the Executive Officer of a DropShip, JumpShip, or WarShip.

SLDF

The first Star League did not use this rank; Majors were promoted directly to Colonels (or Commodore if a member of the Star League Navy).

Draconis Combine Mustered Soldiery

In the DCMS a Lieutenant Colonel is called a Chu-sa. Like other Inner Sphere militaries, they command battalions of troops. In the Draconis Combine Admirality, the equivalent rank is Sho-sa. As their symbol of rank they wear an apple green katakana numeral 2.

Armed Forces of the Federated Suns

This is the AFFS equivalent to the Lieutenant Colonel rank used by other militaries. The Leftenant Colonel is usually the executive officer and second in command of a regiment of ground forces. The Leftenant Colonel handles most of the daily administrative chores of the regiment so the commanding Colonel has more time to formulate regimental strategy. The equivalent rank in the AFFS Navy is Light Commodore.

Leftenant Colonels and Light Commodores wear an epaulette with one broad band and one narrow band as their rank insignia.

Capellan Confederation Armed Forces

After Sun-Tzu Liao became Chancellor of the Capellan Confederation, he created a new rank system for the CCAF as part of his Xin Sheng movement. Officers who hold the rank of Lieutenant Colonel are called Zhong-shao; Naval officers add Kong- as a prefix to show their rank of Kong-zhong-shao.

As part of their unique position in the Capellan Confederation, the Warrior Houses use the rank of Ying-zhang for the commanding officer of the Warrior House infantry battalion. Usually this officer also acts as the Executive Officer of the 'Mech battalion.

Regardless of service branch (CCAF or Warrior House;'Mech or infantry), officers use a brass bar with three silver pips as their rank insignia.

Free Worlds League Military

In the FWLM the Lieutenant Colonel rank was created to allow Majors to command regimental sized formations. This promotion was only supposed to be taken when a Major was destined to be promoted to Colonel or a until a new Colonel took command of the regiment. In reality this rank can be held by either regimental commanders or senior battalion commanders.

The Clans

The Clans do not use this rank. Instead a Star Colonel is likely to be assisted by a senior Star Captain.

Comstar/Word of Blake

Due to their unique force structure, the Lieutenant Colonel rank doesn't exist in the ComGuards or Word of Blake Militia. Instead, the commanding officer of a Level III (battalion sized formation) is either an Adept or Demi-Precentor.
