(A) "1 point for each battle card; up to a maximum of 2x"
Is the 1 point cost for individual stands (i.e. 1 point/stand) or for all stands of that type?
(B)"The battle card is expended when used and may not be used again."
If for all Stands then if I purchase x2, can one 'Charge Through' all of that type twice, or is the x2 to mean that just two stands can do it only once?
Thanks in advance for Clarification. (have dug my Late Crusader out again.

Herewith the Full Rule
This battle card can be played to allow eligible troops to pass through friendly close order foot stands.
The army list indicates which troops may have the Charge Through battle card purchased for them.
A Charge Through battle card is purchased for all stands in an eligible troop entry — not a particular stand. (Knights) The army list also indicates which troops may be moved through.
Cost

1 point for each battle card; up to a maximum of 2x
Playing a Charge Through battle card only applies to one tactical move and its effect ends when that tactical move is over.
The battle card is expended when used and may not be used again.
