c. At a minimum depression of 5, the main gun shall be capable of being
traversed within the zone from 90 each side of the vehicle rear centerline to
20 each side of vehicle rear centerline by manual control with elevation and
traverse power switch off. The traverse shall be accomplished without vehicle
interference.
d. At full depression the main gun shall be traversed at maximum traverse speed
within the zone of 90 each side of the vehicle front centerline with elevation
and traverse power switch on. The main gun shall automatically elevate
outside of this zone so that the traverse is accomplished without vehicle
interference.
e. At an elevation of 0 the main gun shall be capable of being traversed within
the zone of 90 each side of the vehicle rear centerline with elevation and
traverse power switch on. The traverse shall be accomplished without vehicle
interference.
3.6.13.12 Gun laying (stationary target, vehicle stationary). From a layoff position
tabulated in table III, the average time required for a total of four, eight, or 12 trials to position
the gunsight reticle within the borders of a 0.25 mil square target shall not exceed that tabulated
in table III. The time for layoff position number three shall be met for an equal number of trials
from each of four different quadrants from target. The time of all other layoff positions shall be
met for two directions from targets. These requirements shall be met by gunner and commander
power and manual controls as stipulated in table III. The results of any series of trials shall not
be used in any other series.

3.6.13.13 Turret and gun control system operation on slope. When the vehicle is canted
or pitched on slopes up to and including 15 turret attitude, the gun control system shall be
capable of gun laying on a 0.25 mil stationary target as specified in 3.6.13.12, table III, except
time limitation, need not be met. This requirement shall apply only to the gunner power control.
The gun control system performance on level terrain shall not be affected in any manner as a
result of vehicle operation on slopes. Combat load of simulated equipment may be employed if
desired.
