Lockheed F-80 Shooting Stars attacking ground targets in Korea with gunfire and napalm in 1951

At 0:13 a Republic F-84 Thunderjet sneaks in.

The F-80 was armed with a battery of six Browning AN/M3 0.50 cal machine guns concentrated in the nose that fired at a considerably faster rate than the AN/M2 that was almost universally used during WW2. One second on the trigger sent a total of about 120 rounds downrange, one can imagine the effect this firepower would have on targets on the ground.
