Self-defense is also an act of war.
To every thing there is a season, and a time to every purpose under the heaven.

and war is not just about killing... in fact often the most effective acts of war are things like blowing up bridges, ammo depots, knocking out communications, spreading confusion and creating false intelligence (counterintelligence) and reconnaissance (going deep behind lines to get information that cannot be gathered any other way), and even helping people escape impending invasion and removing one of the chips the enemy might use against you
when i was considering joining the military, recon was my preferred option... unfortunately i confessed to being a bit mad and the doctors ruled that i was no good for service haha
you chose well... bridges are my favorite things followed by trains, so don't blow them up!
Trains on bridges are just a beautiful representation of ingenuity saving energy
