Having just read a somewhat mind boggling piece in the ADTN about combined arms obstacle integration I was curious about a few things. Most of which I probably shouldn't ask as it's a restricted piece... The one of most concern though was, as a chap who has seen lot's of lovely teeth arm equipment but little of the corps, that I didn't have a scooby what these obstacles might be. Three types were listed in airy passing, Minefield, Anti-tank ditch and crater (?)... what I am curious about is how these all work and whether there are further types of obstacle to be utilised, as in this example, by a commander. The one thing that did confuse me was the use of minefield, as someone has mentioned that we're required to mark up every minefield we lay. If this is the case, barring areas of limited exploitation such as bottlenecks, is the effect therefore of minefields not simply limited to diverting an enemy from their chosen path to the limit of your own minefield?
