Bael and Davram on a hill spying on Elayne's enemies. Bael makes a hand motion signaling for his scouting party to move out.

I just saw in my head him raising his pointer finger and swirling it around like "move out/start engines(?)" from the modern us army/marines. lol

RJ is very military savy.  You can tell he's studied the old warfare methods, too.
