When can DM unit rally in an assualt hex?

[Michael Murphy]

Could the arriving leader also then activate units to rally, instead of attacking?

I believe the answer to this lies with the activation type. The DEM unit in the assault would not be activating by a MOVE/FIRE declaration. To attempt recover a unit must declare a MOVE activation. This plus what Vince points out that the leader cannot activate the DEM unit, leaves them to recover in another action segment.

Oops! That's another one.

Note to self --- reread the rules occasionally. Fortunately, my opponents (me, myself, and I) haven't had a serious problem with this.
