2.7 says you can use reserve markers to buy cards in the Organization Phase OR the Weekly Organization phase.
9.0 Organization Phase. I can find no reference to the use of reserve markers to buy cards.
19.1 Weekly Organization Phase. This rule does say you can use reserve markers to buy cards.
So, can reserve markers be used to buy cards in the Organization Phase?
You are correct this should have indicated 8.0 Strategic Phase., my bad. I changed this late in the design and somehow we forgot to correct that sentence.
[8.0] Strategic Phase
During the Strategic Phase, the following Steps must be performed in order:
A. Allied Card Draw/Discard Step: The Allied player does his Event Discards and Draws (see 5.1).
B. German Card Draw/Discard Step: The German player does his Event Discards and Draws (see 5.1).
Rule 5.1 says:
[5.1] Event Card Discard and Draws
This phase begins by discarding. A player can only retain two cards in his hand before drawing, so he must discard any excess cards in his hand at this time, and may also decide to discard the last two cards, if any.
After discarding (if required), a player draws four cards from the Draw Pile (one by one, playing red-text cards), or Reserve markers (one Reserve Point per card draw forfeited) in any combination, for a total of four, and adds them to his hand or Reserve. The Allied player can take the tan (UK) or green (US) markers in any combination.
He can then spend available Reserve Points to draw more cards if desired, without going over his hand limit of six cards (12.4).
