*shrug* Kindof pointless to get into pissing matches like this, but heck, until we get started, sure. Three aerial drones open up on you with LMG fire, mix of ExEx and SnS, no ground units in sight.
Tachikoma is a rigger, Kouryuu. An AI rigger, at that. No matter how nasty the troll is in combat, there are only a few very specific ways that an AI can be killed. So, barring some specific circumstances, Tachikoma will survive. The drones might not, but Tachikoma will.
