(1) Installation equipment (see AR 420-70 and TM 5-600 series).

(2) Industrial production equipment.

(3) Nonstandard equipment that is locally purchased and has not been type-classified or assigned an national stock number (NSN). However, nontactical (commercial) wheeled vehicles are covered by this pamphlet.

(4) Equipment bought with nonappropriated funds.

(5) Medical equipment covered by AR 40-61.

c. The guidance found in this pamphlet can be applied to any field maintenance operation, regardless of the density of equipment or whether field maintenance support is organic, operational control (OPCON) from a forward support company (FSC), or received on an area support basis at echelons above brigade (EAB) level.
