Question:
Rule 23.B, Staging, states the initiating players units fly a “1-legged transfer mission”. The transfer rules state that transfer missions occur only in the movement and exploitation phase. I assume that this restriction does not apply to staging, otherwise the prohibition against staging of DAS missions would not be necessary. Is this correct?

Answer:
Staging is not a “mission” in itself Staging is a separate concept from transfers and while it operates similarly to the transfer mission, it is not exactly the same. The staging rules detail any restrictions upon this mission and staging may be performed during combat phases.
