Joel 2:8

"Neither doth one thrust another, they march every one in his path; and they burst through the weapons, and break not off their course. They leap upon the city; they run upon the wall; they climb up into the houses; they enter in at the windows like a thief.

"Burst through the weapons ..." is another stern military term, the weapons in view being the defensive weapons employed in warfare, not any kind of clubs used against locusts. The people visited by a locust plague already know the hopelessness of attacking the swarms with any type of "weapons," such things as fire, smoke, poisons, insecticides, and trenches filled with water being the usual defenses. The imagery here is that of a city's defenses being overwhelmed with military force.
