If you are looking at other manufactures you should look for the following for guard.
Normal Infantry
Elite Infantry
Cavalry/Bikes/Outriders
Heavy weapons
Command figures
IFVs (Chimera Chassis)
SP Artillery (Chimera Chassis)
SP Rocket Artillery (Chimera Chassis)
SP Siege Artillery (Chimera Chassis)
SP AA (Chimera Chassis)
ICBM/Scud and transporter like thing (Chimera Chassis)
Flame tank (Chimera Chassis)
Tanks
Super Heavy Tank
Super Heavy Tank with titan zapper
Skimmer/Helicopter anti tank apache like
Skimmer/Helicopter transporter Hind like
Lots of companies do this, though noticeably the Exodus Wars range pretty much tries to do it like GW with the same hulls and stuff
However there is no need to stick with one manufacture. The SHTs could b one company, the tanks another, the chimera look alikes another and the infantry someone else.
