Defuse ? Defuse is unrealistic
Well though that is a thing one has to decide upon if one wants to include it, considering the Difficulty in Ostfront to break through a profer Defense it would be okay to have a undefuseable Satchel. But thats just my opinion, it would depend upon the Layout of the Map.
Though one first should sperate Objectives which can get blown up only by a select Amount of Sturmpioniere/Sapers or Objectives where everyone has a Bomb to blow up the Objective.
I don't know what kind of S&D Gameplay Dirty had in his mind.[/quote
Although defuse is unrealistic they could grab the sacthel and chuck it off the obj sort of a suicide thing.
