" The basic principles of the combat tactics of the different 

 arms are set forth in the Drill Regulations of those arms for 

 units as high as brigades." (Preface, Field Service Regula- 

 tions.) 



"The Drill Regulations are furnished as a guide. They 

 provide the principles for training and for increasing the 

 probability of success in battle. In the interpretation of the 

 regulations the spirit must be sought. Quibbling over the 

 minutiae of form is indicative of failure to grasp the spirit."
