From the mouths of my squaddies come some of the most idiotic and fun ideas! Cajun is right, it's as fun as you want it to be!
Here is a few of my favorites-
Paratrooper attack-everybody ups a plane and deacks an enemy field. Then everybody bails and runs around field being absolute pests until someone catches on or auto-ack pops. FUN FUN FUN
Fake carrier attack-everybody ups a plane that would only come off a carrier, flys NOE until you are about a sector out from the target, then pop(out over the water, duh) so the enemy can see the dar. You would be surprised how many folks up when they think there is a carrier right offshore. The best part is, there will be all sorts of fellows hunting a carrier offshore that does not exist. FUN FUN FUN
Mt Vesuvius shore battery-find an airfield under attack where your shore battery can hit your own airfield. Wait for the enemy vulch to get going good, then start putting those big rounds under the vulchers when they are diving on aircraft trying to get up. WAMMMO! It's like a mini volcano right under those vulching planes. They will never know what hit them! FUN FUN FUN
