Okay, how about the bar at the airfield? No! This is better: The.... ahem... gentleman's club? The loss of such a facility would cause such stress that fighter pilots would be distracted by our nose art. Their accuracy would suffer, until they visited another base with an active establishment.
Bomber pilots wouldn't be affected.
No, I'm not casting aspersions against bomber pilots. I'm just saying they're all old men with wives at home.
Oh, and capturing an enemy base with the facility unfortunately intact would immediately cause 20 minutes of downtime for all participating friendly fighters. (It's so difficult to maintain discipline these days!)
