C.

Always keep in mind the CAUTIONS and WARNINGS.

Perform your "during" (D) PMCS.

After you operate. Be sure to perform your "after" (A) PMCS.

Section III. OPERATION UNDER USUAL CONDITIONS

GENERAL. Before the MILES equipment can be used, it must be properly installed on the M1 Abrams Tank. To speed up procedures, work is organized into various tasks. While some crew members are performing one set of tasks, others can be performing another set.

Before you begin, read all steps in the task and look at each drawing carefully. To help perform a task, most steps have reference numbers to drawings. Do each step just the way you are instructed and in the order in which it occurs in this manual.

DON'T JUMP AHEAD. DON'T SKIP ANY STEPS

If your MILES equipment has a problem you can't fix using this manual, report it on DA Form 2402. To get a replacement, turn in the faulty equipment and the completed form.

TASK ASSIGNMENT. The tank commander assigns crewmen to tasks. The crewman turns to the appropriate section in this manual and performs the required steps in order. Occasionally, the manual may tell a crewman to wait until he has made sure that another crewman has completed an earlier task. On some tasks, two crewmen may have to work together.

Certain steps must be done with the controller present. A controller key, carried only by the controller, is required to reset the system. The tank commander will determine when to call the controller.

Those tasks involving the controller must be done in this order:

The tank commander, loader, and gunner wear man worn laser detector (MWLD) assemblies.

The tank commander should coordinate the tasks, give assistance to any crewman who needs it, and check to make sure everything gets done.

[blocks in formation]

Obtain all equipment needed to install and operate MILES M1 Tank system from your NCOIC. Unpack transit case and verify that all equipment is present and not visibly damaged. Check against illustrations in Appendix B, Components of End Item.

Obtain all expendable supplies and materials (Appendix D) and special tools (Appendix E).

Obtain Hoffman device system for main gun (Appendix C) and blank fire adapters and ammunition trays for all vehicle machine guns.
