The LCAF
The Lyran Commonwealth Armed Forces is the one house force that we have the most information about. The LCAF organizes its battlemech forces into combat teams which are loosely based upon the SLDF line brigades. A combat team would comprise a battlemech regiment, three conventional regiments, and an aerospace wing. The LCAF also organizes its conventional forces into mixed-arm combat teams of four conventional regiments and an aerospace wing. The LCAF follows the SLDF organization with three Combat Teams to a division, three divisions plus conventional forces to a corps, and three corps to an army.
The LCAF is stated to have a total strength of 122 battlemech regiments. There are three things to remember about this number. The first is that all of the Lyran mercenary units are included in this total. The second is that the Tamar Tigers (former 1st Tamar Hussars) are counted as honorary members of the LCAF and fall into this total. And the final thing to remember is that the provincial forces are not counted as part of the LCAF.
The LCAF has the following units:
Royal Guard (5 regiments) – 1st, 2nd, 3rd, 4th, and 5th (the 5th Royal Guards are mentioned on page 87 of the original House Steiner SB)
