[7.29] "Once per game turn each player may designate one Strategy card to be held over for a future game turn to conduct an Offensive, event, or a reaction."
Implies the FO card can not be used to relocate a HQ or for a China OC offensive.
[7.29B] "Other than this restriction, a Future Offensive card may be played any time a player could normally play a strategy card."
Implies the FO card can be used to relocate a HQ or for a China OC offensive.
In the past I have played it as 'can not', is this correct?
You can use it and play it like any card, so it can be used for its OC value to relocate HQ or China Offensive.
