C. C. P. Form 459 December, 1918 FOREWORD Personnel Specifications for enlisted men of the Tank Corps (complete) are herewith issued. It will be noticed that Personnel Specifications include the Army title, the authorization of the various grades according to the Tables of Organization, the corresponding civilian occupation, the degree of skill at the occupation and the occupational symbol (used in the classification of all enlisted men) which are com- monly found in the Tables of Occupational Needs for various branches and corps of the service heretofore published. In ad- dition, Personnel Specifications include a suggested substitute for every civilian occupation and a description of the duties of each grade. Several limitations to the complete, intelligent use of any sort of tables of occupational organization of Army units have created the necessity for tables where the duties of various grades are specified. The Tables of Occupational Needs pre- scribe the trade specialists required to organize and maintain the organization of well-balanced units. The personnel office in preparing a requisition for men for the organization which is forming can from the Tables of Occupational Needs alone get the material for the telegram requisitioning these men. But in making an assignment of the men provided to fill the requisition, more than the bare terms of the civilian occupation required must be taken into account if the assignment is to remain per- manent. For two sergeants, both to be drawn from the same occupation, one to function as a radio sergeant, heavy artillery, and the other as a sergeant, first class, Air Service, the personnel officer would make no choice between two wireless operators, but would in- discriminately send one to the regiment of heavy artillery and the other to the motor mechanics regiment. But when he reads in Personnel Specifications for the particular arm he is consider- ing the following concerning the radio sergeant : 1 Radio Sergeant .... Wireless or buzzer operator 1 Jour. 31w Substitute: Telegrapher. Cares for and operates wireless apparatus and makes repairs under adverse conditions. Re- quired to send and receive fifteen words per minute. while the other, the sergeant, first class, Air Service, is merely defined as 1 Wireless Operator Wireless operator 1 Jour. 31 w Supervises the testing of repaired radio units and accessory wireless apparatus. he will send the man whose card shows more athletic activity ar-c greater mental alertness to the artillery, while the man with more academic ability in radio telegraphy and construction will be sent to the electrical repair company of the motor mechanics regiment, and both will have much better prospects of remaining in this assignment than had a random selection been made merely from the civilian occupation. Frequently the personnel officer will find that the definition of duties describes the limits of duties. From this may be inferred the range of qualifications which the man must possess in order to be of the utmost use to his company. In every case he will find the qualifications stated in terms of what the man actually does, for it has been determined that with such a statement the tables can be used to greatest ad- vantage both by personnel officers and by commanding officers. The limitations upon successfully assigning men in a person- nel office have created another necessity for Tables of Specifica- tion. Not only is some guide required by the personnel officer in making initial assignments, but it is also necessary to point the way for the organization commander. It can not be taken for granted that a man assigned by the personnel officer will in every instance function as it is intended he should. In some instances it has been found not only that he does not so function, but that he is never given a chance to do so. This is not because of any opposition to giving him a chance to demonstrate how far his occupational qualifications fit him for performing Army duties, but because the relation between the civilian occupation and the Army duties is not in every case apparent. In the case of cooks the relation is so obvious that no one could mistake it, but there are other occupations the relations of which to Army duties are not so patent as those of cooks. Right here the tables find their practical usefulness. They enable the company com- mander to compare what the man does in his company with the occupation which most nearly fits him to perform these duties. Then it is a logical step to take the Qualification Cards and the assignment as made by the personnel officer and to place the man in the position where his occupational qualifications relate to the Army function. Each set of Tables of Occupational Needs and Personnel Speci- fications contains the following statement, which prescribes their use: The purpose of these tables is to assist in fitting into the Army civilian occupational experience where it will be util- ized to the best advantage. Because of the scarcity of men possessing trade ability, the occupations specified in these tables have been divided into two groups : (a) Those that are essential to successful operation are known as the MAIN GROUP and are to be provided. ii (b) Those that are desirable but not entirely essential to successful operation are listed under LESS ESSENTIAL GROUP, and are to be fitted in as indicated, provided they are available and are not needed for assignment elsewhere in some MAIN GROUP. In the organization of units requisitions for occupation- alists will therefore, be honored only in order to complete such MAIN GROUPS. Although desirable that any or all of the specialists called for in any LESS ESSENTIAL GROUP should be given a particular assignment, it is best in the first instance to allot them to each unit as a whole, and it is consequently not nec- essary to assign the men of this group to any particular section of the unit ; and where, in the following tables, the totals of any such LESS ESSENTIAL GROUP have been added to any particular section of a unit, it is to be under- stood to have been so done for convenience in accounting and not to prevent the assignment of such specialists else- where in the unit, accordingly as their services are needed. Moreover, since these specialists can not be requisitioned, their presence in an organization depends upon whether they are to be found at the station of formation of the unit. For these reasons, the LESS ESSENTIAL GROUP is in every instance appended to the Tables of Personnel Speci- fications. The utilization of all the resources of supply has provided the possibility of assigning to each organization the trade ability actually required in order to enable the organization properly to operate. Moreover, occupational specialists are quite as essen- tial to successful operation as is equipment used by the organiza- tion in the field. Telegraphers and buzzer operators are as necessary to the complete functioning of a Field Signal Bat- talion as are rifles and bayonets to a rifle company of the in- fantry regiment. In the first days of the present Army the necessity for occupational specialists was usually vague, and in- coherently expressed where it was known ; but now the greater expansion of the Army and the increased specialization of units have made it necessary to secure to the organization performing duties of an intricate or technical nature men who by periods of civilian training at the various arts and trades have become especially fitted to perform these functions. The actual assignment of these specialists is qualified by con- ditions which, owing to the haste in war training, it is not pos- sible to overcome. There are certain occupations necessary to successful operation in the field, which it is not possible to sup- ply in the number stated as essential in the various Tables of Personnel Specifications. These occupational specialists are pro- duced only after many years of civilian training and the indus- tries which produce them are not extensively developed. The number of civilians entering the Army who possess trade ability in of a rare kind is therefore not enough to fill the demand. To meet this condition but one solution is possible : To give men of civilian occupations allied to these rare ones a brief but compre- hensive period of training in the Army specialty they will be called upon to perform. This has in many instances been done, and when the authorization of various Tables of Personnel Specifications in all staff corps and branches and arms of the service is determined, it will be possible by adjusting the supply to the demand to foresee exactly what numbers of these men must be trained to fill the demand. Now that these Tables are in usable form, there no longer remains any reason for the misplacement of skilled occupational specialists. Without good reason misplacements should in no case be permitted. An electrical instrument maker or repair- man must be used in a Field Signal Battalion on the work for .which he is trained, not as assistant cook. Specialists are un- common and valuable. It requires more time to produce a good draftsman than it does to make a bayonet, yet the soldier is pro- hibited from chopping wood or opening cans with the bayonet, while draftsmen in many instances have been used, not for the task for which their training has prepared them, but for duties for which they have had no training, or which do not challenge their ability. This is wastage of the worst sort, for while the piece of materiel destroyed can be replaced in a short time by another which will function quite as well, the trade specialist lost to the service can not. And at the present time, when every person possessing trade ability has a peculiar place in the Army, specialists assigned by personnel officers to organizations must be thoroughly tried out in the place which they are assigned to fill. The intelligent use of these tables is therefore as important as the occupational classification of the men in making full use of the man -power of the nation.
