item is the total quantity of items authorizedfor the number of equipments supported. Sub-sequent appearances of the same item will havethe letters RE in the allowance columns.Items authorized for use as required but notfor initial stockage are identified with an as-terisk in the allowance column.

(2) The quantitative allowances fororganizational level of maintenance representsone initial prescribed load for a 15-day periodfor the number of equipments supported. Unitsand organizations authorized additional pre-scribed loads will multiply the number ofprescribed loads authorized by the quantity ofrepair parts reflected in the appropriatedensity column to obtain the total quantityof repair parts authorized.

(3) Organizational units providing main-tenance for more than 100 of these equipmentsshall determine the total quantity of parts re-quired by converting the equipment quantityto a decimal factor by placing a decimal pointbefore the next to last digit of the number toindicate hundredths, and multiplying the dec-imal factor by the parts quantity authorizedin the 51-100 allowance column. Example,authorized allowance for 51-100 equipments is12; for 140 equipments multiply 12 by 1.40 or16.80 rounded off to 17 parts required.

(4) Subsequent changes to allowances willbe limited as follows: No change in the rangeof items is authorized. If additional items areconsidered necessary, recommendation shouldbe forwarded to Commanding General, Head-quarters, U.S. Army Weapons Command,ATTN : AMSWE-SMM-SA, Rock Island,Illinois 61201 for exception or revision to theallowance list. Revision to the range of itemauthorized will be made by Headquarters, U.S.Army Weapons Command based upon engineer-ing experience and demand data, or TAERSinformation.

1. 30-Day DS/GS Maint enance Allow ances.Note. Allowances in GS column are for GS main-

tenance only.(1) The allowance columns are dividedinto three subcolumns. Indicated in each sub-

column, opposite the first appearance of eachitem, is the total quantity of items authorizedfor the number of equipments supported. Sub-

sequent appearances of the same item will havethe letters RE in. the applicable allowanc$columns. Items authorized for use as requiredbut not for initial stockage are identified withan asterisk in the allowance column.

(2) The quantitative allowances for DS/GSlevels of maintenance will represent initialstockage for a 30-day period for the numberof equipments supported.

(3) Determination of the total quantity ofparts required for maintenance of more than100 of these equipments can be accomplishedby converting the equipment quantity to a dec-imal factor by placing a decimal point beforethe next to last digit of the number to indicatehundredths, and multiplying the decimalfactor by the parts quantity authorized in the51-100 allowance column. Example, authorizedallowance for 51-100 equipments is 40; for 150equipments multiply 40 by 1.50 or 60 partsrequired.
