Who moves first in multiplayer battles?

[the_iron_duke]

In particular, skirmish custom battles. Is it always Side A or is it randomized?

Thanks in advance.

Side A always gets first turn, but only deploys.

Side B then deploys and can then immediately move. (To avoid delaying the game by an unnecessary return of turn)

Neither side can see the other's deployment while deploying.
