Now that I think about it in reality the mines placed between the shingle and the sea would likely only have been anti-tank versions. Anti personnel mines would have been placed at the top of the shingle to avoid being washed out by tides. I suppose they could have anchored some or maybe used stake mines but not trip wires. You could also add the achtung signs on the flanks at the top of the cliff as they would likely be mined. Anyway the barb wire on the clips sounds good.
Looking at the
wiki the beach length to the shingle bank is very real. The distance from the shingle bank to the cliff I don't know, as only the max distance of 200yds is given. Not having anything more than top view to go on I am guessing maybe someplace from sector Fox Red to Fox Green is possible. BTW if you want to add a DD Tank for eye candy the wiki has a picture on one on the beach with its 2 snorkels on the back and another one is
here. Not many polygons to add to the already static Sherman models that have appeared in a few maps (e.g. 2bit's tiger_110 map) if the fps allows.
As to the waypoints I am going to try to get the axis engrs to use the upper trench route to an engr camp by the far gun ("East anti-tank gun"). I think the axis bots are losing because they needed to be in the east sector to have time to defuse and don't have time to fight inside between the 2 spawns.
