What else can one hide?

Lets assume we are going to put on the table some category of units - tanks (stands representing 10 each) and infantry (in stands representing 80-120).  What can we use that to hide?

• The stands may have variable strength depending on casualties - say two or three steps available.
• They may also the straight-up strength-zero dummies.
• It is easy to hide which is the command stand, if it matters.
• An indicator can show which stand has the FOO with it.
• Small support weapons (MGs, light AT guns, etc) can be a marker under an infantry stand until it should be deployed.  

Concealment is critical to understanding WWII, and a set of grand-tactical rules has to acknowledge that.
