They have some pretty standard meanings . . . so a heavy star, IMO you are expecting anything from 3H & 2M to 4H & 1A . . . maybe 2 depending on the Clan or if they are Gargoyles. If you look at the Quad-Vee entry info, I want to say one source talked about how the Horses threw who they were fighting for a loop b/c they organized them in vehicle points- so surprise! Falcon/Wolf/Bear, you now face a pair of Quads when you were expecting tanks!
I think that right there says they do not spell out the machines. Also, since they all come from the Star League, they started with the same baseline definition of 'Striker Lance/Company' . . . and again, its the machines that are not revealed. They share the codexes of the warriors involved- its part of how the trueborns who kill every freeborn they face know who to look for . . .
