Why only fighters getting all fun? We decide to try new tournament format to restore fairness.

There will be two teams. Attackers and defenders. Goal of attackers is to build prop attack planes armed with bombs and rocket pods. Planes that could breach enemy AA defense and destroy their base. Defenders must build AA units (stationary flak cannons, AA vehicles e.t.c.) armed with 12,7 mm machineguns and 20 - 88 mm cannons (you can find them inside challenge file).

Any player can build up to two crafts but only for one team, so choose wisely. Your creations can be replicas or fictional, but only successors of this challenge can participate.

So rules:
- Only prop engines for planes with max. speed on-the-deck 550 mph.
- No guided missiles for everyone.
- Lesser caliber - higher accuracy, but lesser fire distance and damage dealt. More barrels - more time to reload and, if it >45mm bigger "hitbox". More payload on plane - lesser chance to survive during run-up. If you take only bombs - your plane will use dive bombing tactics. If you take only rocket pods your plane will use hedgehop.
- Dive bombers will be vulnerable to 45+ mm AA, but lesser calibers will be almost useless against them. Planes attacking their targets on hedgehop will be extremely vulnerable to 12,7-20 mm AA. 20-45 mm AA will be usefull against classic attack planes tactics.
- Every unit strenght will be determinated by judges. Each plane will fly in wing including 5 copies, so total planes number will be equall to (Attackers players number)*5. AA units will form coordinated artillery battery to defend base. Total AA units amount will be calculated after planes in balancing reasons so the contest winner will be determinated by quality, not by team players number.

Some advices: rocket pods great against AA units, but bad against buildings. Defenders base contains bunkers that can be destroyed only by dive bombers. Mobility matters not only for planes, more speed - more chance to avoid bomb but lesser armor. Armored stacionary AA units can survive rocket attack.

Every entry will get upvote.
Every player in winners team will get 3 upvotes.
In every team will be awarded two best works (5 and 10 upvotes).

Again, EVERY entry must be a successor.

Deadline: August 22 2016.
