I was getting all excited about this combo and trying to find a place to put it but then I realized that in practice, this combo is only ever going to happen if your opponent allows it.
Unit with Dispatch Runner sets a skill action and grants a melee attack to the unit with War Crier. The unit with War Crier gets a stun token. The unit with War Crier reveals a skill action and then moves that Stun token to an enemy unit. That's all pretty awesome.
I figured that I needed to find a unit with the skill action on the left dial so that the stun token couldn't be used to just cancel the skill action that was set. That's when I figured I should verify the timing of the stun token.
RRG, pg. 8:
"Stun: When a unit that has a stun token reveals its
command tool, that token can be spent to cancel
that unit’s modifier. The unit still resolves its action."
That's what kind of crushed my dreams. It looks like the stun token is spent as soon as the dial is revealed so your opponent has the option to spend the token before you are able to give it to one of their units. I guess the only way that this works is if you've got a pair of units with Dispatch Runners and a unit with War Crier. Your War Crier unit will get two melee attacks, and then receive two stun tokens. When you reveal your dial, your opponent may or may not spend one token to take away your modifier dial, and then your skill action passes a stun token to an enemy unit.
Am I missing anything with all that?
