traverse or elevation and depression. For combined traverse and elevation/depression
layoffs, the time requirements apply to an equal number of trials from each of four
directions from the target.
c. For acceptance testing, sighting on the specified target shall be performed for
positions 3, 5, and 7 of table IV. Two trials shall be made and the average time shall
be used for determination of compliance.
4.6.4.9.3.4 Gun laying on moving target and tracking accuracy. To determine conformance
to 3.5.9.3.4, tests shall be conducted in accordance with the following:
a. Testing with the gunner's and commander's controls shall be conducted with the
commander's control in the power mode and with the gunner's control in the
stabilized mode. A suitable turret tracking instrument with timer, recorder and
calibrating device shall be used for performing tests. Tests shall be conducted in both

b. For acceptance testing, traverse rates of 0.5, 3.3, 32.6 and 65.2 mils per second as
shown in table V shall be used.
4.6.4.9.3.5 Operation on slopes. To determine conformance to 3.5.9.3.5, tests shall be
conducted in accordance with the following:

operating in the non-stabilized mode. Tests with the commander's controls shall be
conducted with the vehicle operating in the stabilized mode. Manual control tests
shall be performed at the gunner's station.
b. For acceptance testing, sighting on the specified target shall be accomplished for
positions 3, 5, and 7 of table IV for power and stabilized modes. Two trials shall be
made and the average time used for determination of compliance. One trial shall be
made for positions 3 and 5 for the manual mode.
4.6.4.9.3.6 Stability of operation, vehicle stationary.
4.6.4.9.3.6.1 Nonstabilized mode. To determine conformance to 3.5.9.3.6.1, for the

OFF and engine inoperative:
a. Using the gunner's telescope and manual elevation handle, aline the main gun on a
