I guess that would make more sense then. I had thought it was being rigged by the "teams" explosives, not the "enemies" explosives, like how it is in most games. Actually, that makes it seem more interesting.
So, this is something I have been wondering about since the Alpha. Why does the Security Forces use a cellphone when destroying weapon caches, while the Insurgents use an actual detonator? It's as if the Security Forces are using IED's, while the Insurgents are using proper explosives. I don't know if its just me, but I feel like it should be the other way around. Unless the devs accidentally did this or I'm an idiot, I don't know. Regardless, it's not game breaking.
