CO-OPERATION.
The necessity for co-operation between the machine guns taking part in any particular action cannot be overestimated.
Not only should the individual guns of a particular unit work upon some definite plan for mutual support, but the sections of all units that are operating together should co-operate with a view to obtaining the best results from their combined actions. This cannot be done in action unless previously practised. Therefore attention should be paid to training numbers of guns to operate together for some specific purpose.
