This piece is excellent are marking naval mines. The only problem is that it isn't colored, so it can make identifying who's mines are whos a bit of a problem in the late game.

I use these accessories to build out my Axis and Allies Kings and Kaisers or Global 40 games. The details are excellent, and they add that authentic touch. I highly recommend them.

I bought these because I have decided to play a hybrid of Global War and Axis and Allies using most of the Axis/Allies rules still but adding quite a few from The Global War game including the map which I just got a couple of days ago. Overall, I have about three pages of my own house rules that I created or borrowed or tweaked from Global War for my hybrid game. The naval sea mine markers are a great addition to giving more depth and detail to the game. Currently I'm testing the gameplay with these and so far my friends like the addition and my rules. These are awesome.

small but detailed which is perfect for the board!

These acrylic pieces are great! Super clean - TY!

I really like these markers. I bought them for use in A&A 1940. The production is very good with crisp colors and edges. As in the case of the Airfield and Naval Base Markers, now you can upgrade from the drab OOB pieces to something more noticeable. They look really sharp on the board. Pieces like the sea mines let you add a bit more tactical depth to the game which may end up being a strategic game changer. For my house rules, I use sea mines which may be purchased for 10 and placed in coastal sea zones. Any ships making combat moves (friendly or enemy) through that sea zone is attacked in the same manner as aircraft would be by Anti-Aircraft units in the older rules. During amphibious assaults, transports carrying units are actually taken as casualties first. Sea mines remain on the board, but can be removed by destroyers by having a battle with them (assuming there's no enemy ships in the zone.
