right. combined arms. for an RCT thats at minimum..
124 mechs
372+ vehicles (three regiments)
3360+ infantry (three regiments )
40 aerospace fighters (2 wings)
one battalion artillery
with more vee's, fighters, infantry, and artillery being typical.
of course, 1st militia is described as being an LCT type formation, which would make it:
52 mechs
240 vehiclesand since Filtvelt doesn't use battle armor the battle Armor regiment is likely replaced with multiple regiments of conventional infantry.
in both cases, the mech strength of the force is minimal compared to its over all strength.
and notice is says "infantry regiments".. but only "mech units".. this combined with the LCT description of the 1st militia would support an LCT style organization for all the militia. minimal mech forces, very heavy on vehicles and support units.
as i said.. the evidence supports Filtvelt pulling
a Kowloon, or as close as you can get in canon Btech.
that said, i've posted up a question in the 'ask the lead developers' section in hopes of getting a definitive answer.:
