The bullets pouring out like torrential rain swept behind the galloping Saber, missing her by a hair, and scattered raging sheets of water like the streams of an upward waterfall.

Regardless of the size of the caliber, something on the level of mere cannon shells pose no threat to Servants at all. This is especially so with Saber, whose physical abilities would allow her to evade them with no difficulty, and even deflect the shots back with the blade of her sword if she wanted to. However – no matter how extraordinary the Heroic Spirit may be, the 12,000 rounds-per-minute of the pride of America's General Electric, the M61 autocannon, presented an unmanageable amount of shots. Worse yet, as a weapon carrying the properties of a Noble Phantasm due to Berserker’s prana, a single shot would instantly be fatal.
