Usually I'm a careful player and seldom commit team kills but when playing as sapper this happens too often. This frustrates me a bit because it is very difficult be a sapper and destroying obstacles without endanger your team and get kicked from the server.
My two suggestions to warn my teammates of a prepared satchel:
1) At the moment we have a general warning which indicates that a satchel was laid somewhere in the map. In my opinion this warning should only be shown when you are close-by. Now there are just too many warnings and you start to ignore them.
2) There could also be a default shout when laying the satchel that warns the nearby comrades acoustically. Americas Army has this default shout when throwing a grenade. Of course then there has to be a button to suppers the default shout because sometimes you don't want to warn the enemy.
