Can a Warrant Officer be assigned as a Company Commander for a Recruiting Company?

Key Resolve 2013, Korean battle Simulation Center. Their S3 was a MI CW4. Dude had no clue about "operations". Guess who got assigned to "assist" him? Guess what his first words were? "I'm so glad you're here sir. I have a doctor's appointment, I'll see you later." "Later" wound up being 2 days later. lol
