Either WBNN or GWX Mission Orders will sent you orders to go to scripted events such as the sinking of the Bismarck or Dunkirk. Both mods will also send you the regular scripted messages but Mission Orders Lite will only send you to the scripted events and none of the others. It's made for GWX (either 1.03, 2.0 or 2.1) so unfortunately only supports GWX and not the other supermods.
