Other forms: blockades
A blockade is cutting off supplies to force a surrender. Impose a blockade, run the blockade, a naval blockade.
In international law it is an act of war, which is why states reach for quarantine or interdiction when they want the effect without the word. It hurts civilians first and soldiers last, and that is one of the standing arguments against it.
