I'll kick off discussion with a few ideas of my own. For "battle cry," it could be something simple like grahzaan (lit. "battle-shout"), nahzaan (lit. "fury-shout"), or zindrein (lit. "triumph-roar").
Dreh might be a good root for a word for "to execute/carry out."
Not all of these have to be compound words or rooted in existing words either. Some words such as "to moor" might be better off as standalone words.
I won't be around for much of the day, but Mirkilaar will be here to help along with discussion. Share any ideas you may have and be sure to comment on any that you like!
