I'd like....
More ships,especially wider variety of merchant ships, some German destroyers, British corvettes, etc.
More ground objects, especially 'generic' stuff that can be used in more scenarios.
More vehicles, especially Brit stuff like Bedford trucks, etc.
Also to have trucks that can have artillery 'attached' for towing, and so on.
Some more bunker objects that will actually allow artillery to fire when placed 'inside' them.
This would all be great, if only....
