D-Day Omaha Beach Skirmish Easy Green/ Easy Red sectors

This is a skirmish map I am making on the US, British, Canadian Operation Overlord. It is of the Easy Green and Easy Red sectors of Omaha Beach. The player will be playing as the Americans in charge a small 20 man squad (although able to recruit near by soldiers). The first three points will be along the shingles of the beach at this point the player will have no reinforcements although ai will still be landing on the beach after capturing these three points, the barbed wire along the shingles will explode allowing the player to advance, the player will gain access to the artillery strikes(relatively cheap) LVT4 (pretty expensive) and possibly the Sherman-DD (expensive) depending on if I can get it into the editor, and the arty will stop hitting the beach (answer to that in the next mission!).

The next three point are located behind the bunkers one on a bunker past the beach, one on a flack 38 position, and the last on an mg position. After capturing this the player gains air strikes, although expensive are much more accurate and efficient than artillery strikes for things like bunkers and fortified positions.

After this the third set of points and possibly the last are located behind, one on a hill with aa and a bunker, one on a forward station of barracks underground! (not completely mapped), and the third is not mapped. The reason why the vehicles are expensive is because they were hard to come by as many sank in the channel.
