A PROPOSED METHOD OF FIRING AT MOVING OBJECTS AT 
MODERATE RANGES. 
BY 
CAPTAIN J. U. COATES, R.A. 
Fire to go regularly through the battery, always recommencing where 
it last left off. 
When using time shrapnel, never more than four guns to be actually 
loaded at the same time. The remainder to stand ready with fuze set 
and gun laid. This is necessary to avoid an undue amount of rounds 
acting on graze. 
The following examples explain themselves. 
1st Example using Time Shrapnel, 
Infantry advancing 100 yards per minute. 
A delay of 15 seconds is allowed for giving the change of range. 
Rapid fire is taken as one round in seven seconds, and ordinary, one 
round in 15 seconds. 
Time available for fire at each range 1 minute 45 seconds, giving 
15 rounds of rapid, or 7 rounds of ordinary fire. 
Words of command. Result. Remarks. 
C Fuze 18 (or fuze set for percussion) is 
_ < given to ensure burst on graze for 
” ( ranging rounds. 
— 'These rounds being loaded with fuze 18 
— | will act on graze.

1 If the bursts are too high to be well observed give “ Stand fast,” and reduce the range by 
60 feet, leaving the fuze as before. This will not affect the distance of burst, but merely reduce 
its height. 
At 2000 yards an alteration of 50 yards reduces its height by about 10 feet,
