Will there be ex packs, or something like ex packs in fh2? I Love settin up traps on el alamein with the SAS kit. Although its tough because your only allowed to put down like 9-14 (I forget), and the flag radius's are to large to cover. They are still fun, and it would be nice if they added some other neat trap type deals. Car bombing was fun :P (tough to do with a satchel)
For now only timed satchel charges are planned, but who knows, maybe remotely detonated explosives might find their way into FH2 some day...
I don't think they were used much in combat though, but feel free to correct me if I'm wrong.
Plunger operated wire connected charges were the nearest equivalent to expacks. This was a common form of demolition - just look at all the old war movies with people waiting to push the plunger, destroying trains etc.
I think the expack represents this quite well.
Need some kind of range limit, or a trailing wire (if possible) to represent the cord.
