When a card allows the player to order a number of units equal to their command, is this number reduced by any cards that are not 'in your hand' by being placed on the 'Square Track', or is the number always the total Command value?
A fast view into the rulebook page 6 gives the answer,
• Assault Command cards allow you to order a number of
units equal to your side’s “Command.” The Élan and Rally
Command cards allow you to roll dice equal to your side’s
“Command.” A player’s Command is equal to the number of
Command cards in a player’s hand including the Command
card just played.
Note that each unit in square reduces that side’s Command by
one as one card is randomly removed from the player’s hand
and placed on the Infantry in Square Track. Any in square unit
that comes out of square or is eliminated increases Command
by one as that card is returned to the player’s hand.
