for replacement. Tools requiring routine maintenance are turned in to CTR for repair and reissue. Requisitions will be submitted through prescribed channels for replacement items.

PREPARING REQUISITIONS

As a crew leader, you should become familiar with forms that are used to request material or services through the Naval Supply System. Printed forms are available that provide all the necessary information for physical transfer of the material and accounting requirements.

Two forms used for ordering materials are the Single-Line Item Consumption/Management Document (Manual), NAVSUP Form 1250 (fig. 1-1), and the Requisition and Invoice/Shipping Document, DD Form 1149 (fig. 1-2).

As a crew leader, you are not usually required to make up the entire NAVSUP Form 1250; however, you must list the stock number (when available) of the item, the quantity required, and the name or description of each item needed. This form is turned in to the company expediter, who will check it over, complete the rest of the information required, and sign it. Then it is forwarded to the material liaison officer (MLO) or supply department for processing.

You are not likely to use DD Form 1149 often since the items most frequently ordered are bulk fuels and and lubricants. This form is limited to a single page must contain no more than nine line items. It is not necessary to fill in all the blocks on this form when it is used as a requisition.

When ordering material, you need to know about the national stock number (NSN) system. Information on the NSN system and other topics relating to supply is provided in Military Requirements for Petty Officer Third Class, NAVEDTRA 10044-A.

TIMEKEEPING

In a battalion deployed overseas, as well as at shore-based activities, your duties can involve the posting of entries on time cards for military personnel. Therefore, you should know the type of information called for on time cards and understand the importance of accuracy in labor reporting. You will find that the labor reporting system primarily used in Naval Mobile Construction Battalions (NMCBs) and the system used at shore-based activities are similar.

A labor accounting system is mandatory to record and measure the number of man-hours that a unit spends on various functions. In this system, labor utilization data is collected daily in sufficient detail and in a way that enables the operations officer to compile the data readily. This helps the operations officer manage manpower resources and prepare reports to higher authority.

A unit must account for all labor used to carry out its assignment, so management can determine the amount of labor used on the project. Labor costs are figured and actual man-hours are compared with
