[Rules] APC's in assault?

[Schoenwulf]

The transported unit cannot add its firepower while loaded. The APC may unload before assault combat, its former passenger may contribute in the assault.

Thanks for the quick response, and am I understanding this correctly as follows? ....the APC and transported unit would first do a "move" activation in the hex adjacent to the enemy to be assaulted; this would allow the unit to disembark, with both units possibly risking opp fire from the adjacent unit(s). Then in an action segment in the next turn, both units could do a "fire" move for the assault, assuming that either a regular good-order leader was also in the their hex, or in an adjacent hex from which that leader could order the assault.
