Brace pikes for infantry, building a phalanx

[Kriegstofu]

Hello,
Since this is a teamwork based mod it would be cool if pikes get the ability to get braced, like in some mods for M&B
so we could build a phalanx and help archers against Cavalry even more and if we got much pikes we could build a phalanx (wall array, with long pikes)
