FM 3-19.4
determines that platoon right (left) will be
more appropriate, he may request it.
Adjusting at extreme distances may be
easier with two guns firing. The normal
interval of time between rounds fired by a
platoon or battery right (left) is 5 seconds. If
the observer wants some other interval, he
may so specify.
■ Method of control. Use the following
methods of control: Fire when ready is
standard and no request is required; use at
my command when weapons fire at the
observer's command; use cannot observe
when fire will not be observed; use time on
target when rounds land at a specified time;
use continuous illumination when the FDC
willdeterminewhentofire;usecoordinated
illumination when illumination rounds are
fired only when the target is engaged; use
cease loading when missions have two or
more rounds in effect, causing the firing unit
to stop loading rounds; and use check firing
when there is a temporary halt in firing.
• Danger close. Include the term danger close in
the method-of-engagement portion of the call for
fire when the target is within 400 meters of any
friendly troops or mortars and 600 meters for
field artillery. When adjusting naval gunfire,
announce "danger close" when the target is
located within 750 meters when using naval
guns that are 5 inches or smaller. For naval
guns larger than 5 inches, announce "danger
close" when the target is within 1,000 meters.
The creeping method of adjustment will be used
exclusively during danger close missions. The
FO makes range changes by creeping the rounds
to the target using corrections of less than 100
meters.
