II.—By fire at the belt and specially armoured or so-called “ vital 
parts :—This has been termed the “ primary attack ” but it 
may be better to call it “ attack of belt and primary parts ” or, 
briefly “ belt attack.”^

change of objective,

II.—Each gun group commander should be provided with a small 
red banderole to be used as follows :— 
(a) Red banderole to be stuck in the ground when the 
group is loaded. 
( b ) Red banderole to be lowered immediately the group 
has fired. 
These flags should be placed so that they can be seen by the 
battery commander and are intended as an assistance to that 
officer in indicating what groups are loaded. 
III.—In order to save as much time as possible, the following system 
for arriving at the “ speed ” and “ deflection ” correction is 
suggested 
Battery commander ... Speed. 
T-x f Now * * * stop 2500 
X (any range). 
The interval of time elapsing between the words “now,” 
“ stop ” represents the time taken by the objective to alter its 
range by 50 yards, which time is taken by the battery com¬ 
mander in seconds with a stop watch. 
The correction for speed is then at once ascertained by 
reference to the tables. 
“ Deflection ” is found in a similar way. 
IY.—To obviate the necessity of a battery commander writing his 
orders and making the calculations necessary for “ speed,” 
&c., corrections, it is suggested that he should have on his 
staff a quick, neat writer to do all this for him. His atten¬ 
tion need not then be distracted from his own particular 
work—viz., observation of fire.
