What do you do to boost morale with your Joes?

Nothing boosts moral like time off. Period

You have received good advice from the other respondents. The truly best thing and I am summing up what everyone else has said is give your Joes some down time but keep it informally organized with a meal (BBQ is always good) letting the troops show their cooking skills. Let them let down their hair but don't let it turn into a gripe session! Keep it spontaneous.

Dress problems in timely manner will always boost moral! Soldier want to know you care and the best way to show that is by listening to their concerns and provide solutions when possible.
