So what happened after?
Did Blake (May his name be blessed) and Toyama mouthball these units or did they have these crack troops train new soldiers to have just i case any othe Great Houses would decide to attack and seize a HPG station? IF so how and where would these new soldiers be trained? Sanhurst Academy was mainly a ROM training facility and did not have Mechwarrior/Military training until much much later?
FM: ComStar tells us that after Silver Shield, ComStar mothballed most of its military equipment. When ROM was founded, they got some of the equipment, but this was mostly infantry equipment and vehicles. The guy that looked for the Minnesota Tribe got some Mechs and fighters, but afterwards they went back into mothballs.
So no. No secret force or training facility.
It always seemed sort of...naive. I would've kept it around for a while, just incase someone did decide to jump Terra, but officially the units were disbanded after Silver Shield. (exact date unknown, but before the creation of ROM in 2811 atleast).
