Mines Navel and land

I know we have talked about Navel minelayer however i don't think that got going but i do think that would be good to ad but one thing i did not see is mine layers for land units or and mine sweeper.

for Minesweepers some thing like infantry with ability to sweep or tanks like the sherman crab tank.

Mines were very use full during the battle of kursk the russian used 1000s of them

I am sorry if this has been posted before but i could not find it... exept the part about navel minelayers/sweeper.
