[quote=@NecroKnight]Since Goodneighbor is expanding and has armed Triggermen outside - how would the reaction be?

That depends on the Triggermen.

If they saw an armoured figure accompanied by heavily armed robots and decided to open fire on them, the Robobrains would attempt to wipe them out to keep Isabel safe. If the Triggermen decided they weren't being paid enough for this shit and bugged out, the Robobrains would ignore them.

Just being armed wouldn't automatically be seen as an aggressive action, but if one of them stepped up to Isabel and pointed a gun in her face, that would be met with lethal force.
