DOtF - Operation Crusader question

By ptconfer2429, in Tide of Iron

In DOtF - Operation Crusader how does the Disrupt Medical Supplies card work? It states that "Until the start of the next Command Phase, your opponent's squads receive 1 fewer defense die...".

Since there are no squads in this scenario...

A) should this card be removed from the deck prior to starting the game

B) would this card apply to Tanks

C) should the card remain in the deck but not apply to the tanks in the game. In effect be worthless when drawn?

Thanks for all replies...

Option C, is my take on things.
