C Force Sustainment Data and Calculations

Table C.1 provides the resupply requirements of the command, ground combat, and combat service elements (i.e., the landing force). Tables C.2 and C.3 detail the daily air delivery capacity of the MV-22 and CH-53. All three tables are used in determining the percent of resupply requirements met by air deliveries as shown in Chapter 4, Table 4.3.
