Well theirs no direct ToE of a LCT, what we do know is that effectively it's
LCT
Mech Battalion
-4x Companys
2 or 3x Calvary Battalions (Fast tanks such as hover)
2 or 3x Heavy or Assault Tank Battalions
1x Artillery Company
1x Battle Armor Regiment (4x Btlns) -not all may have this much (at lest in the immediate post Jihad)
Unknown size VTOL unit (likely Btln or larger) -Recon and Transports for the BA
Unknown size Infantry units in supporting roles (I.e. Security and engineer) -at most a btln of each is likely but likely verys from unit to unit
And what ever staff and service elements you feel is appropriate.
However the entire unit is intended to fit on a single star lord (six Dropships), though in practice probably dose not quite make it, out side of heavy use of cargo dropships, or slim formations.
