The seizure of ground likely to be of use to the main body—particularly artillery positions—must be the first consideration of machine guns with the advanced-guard infantry, once the infantry are in action. That they can hold these unsupported is certain. "There never has been and cannot be such a thing as a successful attack on a line of machine guns in a favourable position in action, until the machine guns have been well battered by artillery fire," says Lieutenant Parker in his book Tactical Organisation and Uses of Machine Guns in the Field.
In the cases where the infantry of the advanced guard forms the main guard, the battery of machine guns should march with the foremost body of troops and should never march in rear, where they are useless, and where, if on a road, they can only be moved up with difficulty.
