7. The trials for direct laying will be with different deflections and
ranges; for indirect laying with different deflections and deflection
differences; for laying for range, with different angles of site and
ranges. The trail will be shifted in three trials at direct laying.
8. Changes in setting of scales required of men will not exceed the
following: Deflection scale of peep sight, 15 mils; of panoramic sight,
200 mils; deflection difference scale, 30 mils; corrector scale, 10
mils; angle of site scale, 10 mils; range scales, 800 yards. At direct
laying the deflections announced will be between 6370 and 30. At direct
laying the cross level of the tangent sight will be thrown out of level
by the examiner for the trials requiring shifting of the trail.
In time trials, time will be taken from the word at which the candidate
is instructed by this order to commence his trial to the candidate’s
“Ready,” or to the last word of any announcement required. No credits
will be allowed if the candidate performs any part of the trial after
this interval or if the time taken exceeds the maximum given in the
appropriate table of those shown hereinafter.
Should any trial be vitiated through the fault of an examiner, of an
assistant, of the sight or other instrument used, that trial will be
void and the candidate will be given immediately another trial of the
same nature.
Direct Laying.
12 trials: Six with the peep sight and six with the panoramic sight.
The target will represent a shielded gun and caisson and will be
placed, as nearly as practicable, at a distance of 1,000 yards from the
gun used in the trials.
The candidate being seated on the gunner’s seat, an officer of the
battery commands, for example:
1. Target, that gun.
2. Deflection, 10.
3. 2400.
At the indication of the target, the candidate causes an assistant at
the trail to point the piece in its general direction; =at the last
word of the last command= he sets off the deflection and the range
ordered; corrects for difference of level of the wheels; operates the
elevating and traversing apparatus so as to bring the line of sight
upon the target; calls “Ready,” and steps clear.
No credits will be given in the following cases:
(1) If the sight is incorrectly set for deflection or range.
(2) If, when the bubble of the cross level is accurately centered, the
line of sight is found not to be on any portion of the target.
If the piece is found to be correctly laid within the limits
prescribed, credits will be given as follows
Time in seconds, exactly,
or less than 16 18 20 21 22 23
