 Although many of the "Luftwaffe" gunners were well trained and capable of hitting a fast moving fighter the damage done was seldom enough to stop the attack in time to prevent heavy damage being done to the bomber.The high rate of fire of the MG 15 meant that the small magazines emptied quickly; the time taken to reload often gave a fighter the time it needed to make a successful attack.Efforts had been made to increase the number of defensive weapons, but this also meant that because the weapons were hand-held either more crew members were needed in each aircraft, or the existing crew members could be overworked.
