 Sabotage, again distinguished from terrorism, is an important adjunct activity in war, alongside direct combat.Important targets include supply lines (railroads), infrastructure (bridges, which can be destroyed using dynamite) and communications (telecommunication lines can be crippled by felling a single pole).The developed guerrilla territory must begin to perform its own legitimate manufacturing; again, essential manufacturing processes for the war effort include shoe production and repair, weapons production and repair in an armory, and salt manufacturing.
