Just a bit extra for you when it comes to mines, they suck ! Engineers mark mines well and all, but I have found that even when moving slowly mines can still very deadly to vehicles (especially ones with overlapping areas). The best way to deal with them is to avoid them entirely (often times this is possible), or bombard them with high caliber artillery to entirely remove them, at this point the mine signs will change to a green color and I have never taken any casualties from these.
An example of these green type is below.
