There's some interesting implications here. ICE is well documented as wearing body armor and carrying heavy weaponry. In a planned ambush or head-on attack, an opposing force might be inclined to show up with overwhelming odds and a lot more firepower. It's classic escalation. It would almost certainly be a lethal firefight.

Now that I think about it, regular folks might be inclined to gang-up if they consider themselves under threat. If they're not already.
