SECTION II. DIRECT SUPPORT MAINTENANCE PROCEDURES
5.2 GENERAL
Direct support maintenance provides more extensive tentage repair than is authorized at the unit maintenance
level. Repairs of tent fabric greater than 4-inches in length or diameter and major repairs to other tent
components are done at this level of maintenance. Repair is usually accomplished by industrial machine
sewing and stitching of large patches over damaged areas or cloth panel replacement on the tent. Table 5-1
lists the most commonly used sewing machines.
