(5) Procedures Column. This column tells you how to do the required checks or services. Carefully follow

these instructions. If you do not have the tools, or if the procedures tell you to, have unit maintenance do the work.

(6) Equipment Is Not Ready/Available If Column. This column tells you when and why your equipment

cannot be used.

NOTE

The terms ready/available and mission capable refer to the same status: equipment is on hand

and is able to perform its combat missions. (See DA PAM 738-750).
