We don't need to do thing by the book or army standards. But try to make things sound realistic or reasonable, we are probably not all in the army or experts on the subject (I'm neither, but I like to keep myself informed). But we should keep it fun.
The basic ideas I have are, the Lux fighter ships intercept fake targets, like some Lux fighters are good guys while others play the bad buys in this, equiped with fake rounds of course. No one wants to destroy important expensive space fighters.
The security units meanwhile have a small but sectioned off portioned of the lux to practice fighting off a mock boarding party (Pop up paper targets or holograms since its space age). Using what ever the setting has to offer for non lethal.
Mean while the bridge is in command of all of this. Giving order to everything and everyone like a real life scenario.
Now for the case of Where is Wor´r Danqar in all of this. He could take part of it being the captain of the ship or another idea is he would rather sit back see what his men are capable of doing with out his keen knowledge and know how, and assess it after the drill is done.
