INSPECTIONS

3-1. General Warning: Before inspection, determine that

the weapon ia pointed in a safe direction, that live muada or obstructions are NOT present in the bore or chamber, and that the ammunition is not in position to be loaded. Do not pull the trigger until the weapon haa been cleared.

Make an overti inspection of the weapons for appearance, condition, and operation Manually function, using dummy cartridgea.

3.2. Inspection of Materiel in the Hands of

Troops in’the Field a. &wraL Refer to AR 760-S. b. S’fi.

(1) Inspect parta for wear tb8t would impair

flmctioniIlg of weapons.

(2) Check to be certain that 811 cleaning and preservative matarii, authorized by

pertinent manu&, 8re available.

3-3. Inspection of Materiel to Accompany

Troops Overseas

a. t3twraJ. This inspection is conducted on materiel in alerted unib scheduled for oversea duty to insure that such materiel will not become unserviceable or worn out in a relatively short time. It prescribes a higher percentage of romain- ing usable life in serviceable materiel to meet a

specific need beyond minimum serviceability. b. Spee@. Refer to table 3-l for serviceability

standards.
