I may have missed something on this “attack”. Were shots fired? All I have seen is that a small group of men, carrying “what appeared to be rifles” were observed crossing the border by a NG post whose orders were to “observe and report”. They were also under orders to vacate the post if they felt in danger. It appears that they did exactly as ordered. They were also authorized to use their weapons if attacked, which they did not. So I would assume that they weren’t “attacked” and “overrun” by gun firing drug lords as some seem to want to have happened. If just “seeing” some men with rifles is justification for the guard units to open fire, the Minutemen better be careful if they decide to arm themselves with more "heat" than just handguns and deploy to the border. They might be mistaken for “attackers”.
