My brother inlaw when he was in Iraq, grabbed a bobcat one day and started making a softball field. The next thing you know the entire base was helping build full dugouts, bases, with fences. They had a full diamond, bases, dugouts and fences built within 7 days. It started with just the Airforce, then the Army began joining in and they had several leagues/teams.
The military was in full support of this, as they found it was a huge moral booster for the troops who didn't have much to do on their downtime. My brother sent him some bats, balls and gloves for the guys to use.
He is going back in the next few weeks to a new location and he is hoping he will be in one place long enough to do the same thing. I gotta an OG Salvo I'd love to send to him when he gets that new diamond built.
