Anyone can detect demolitions, but engineers are better at it and stationary troops can detect better as they check around thier location. Just like mines.

They are just fancy mines after all.

But being bigger, then you can snipe them with a sniper class with a proper sniper rifle (not a marksman with an AK, I think)

There is no difference between an EOD team and anyt other engineer class (they just tend to be size 0 and 4 or less men, so slower to clear mines with, but less spottable by defenders if they move slowly)
