(2) Permanent barricades consisting of heavy posts embedded on both
sides of the road or trail, with a gate, or chain stretched between the
posts. The lowest point shall be at least two feet above the ground. The
sign (described in (1) above) shall be attached to the chain. Gate shall be
locked in place.
(3) Firing units shall ensure barricades with clearly visible signs
are in place prior to firing. Specific requirements for each range are
listed in the Special Instructions located on each Range.
(4) Firing units are responsible for ensuring that during hours of
darkness or limited visibility, barricades shall be lighted with chem-lights
or other suitable means.
b. Range Guards
(1) Range guards shall be posted in pairs with positive communications
with the RSO to prevent entry into the danger areas that cannot be
observed, or which do not lie within the established impact areas. Normally,
range access roads are not within this category and do not require a range
guard, except as listed in the Special Instructions on the range or as
specified by the RCO.
(2) Artillery firing units shall post range guards on established
roads when the area “E” of the surface danger zone diagram (refer to
directives in the MCO 3570 series) actually covers the road involved.
Traffic on these roads shall be halted during actual firing. Delays must
not exceed ten (10) minutes at any one time.
(3) OICs/RSOs may post additional range guards, as necessary, to
ensure safety. The arbitrary blocking of roads or the denial of access to
other than a danger area is not permitted.
(4) Range guards shall be provided with a means of positive communication
by the unit posting them. Range guards shall also be provided with
some means of illumination for the identification of their positions during
hours of darkness.
3. Warning Flags and Warning Lights. During daylight hours, the warning
flag shall be raised whenever a unit is on any range. During hours of darkness,
a blinking red light, facing to the rear of the range, shall be in
place. LONGRIFLE will place the unit in check-fire until flags or lights are
in place. The flag is in an ammo can, along with the specific Special Instructions,
attached to a pole at each training facility. When Aviation Units
are conducting night live-fire operations in the Zulu or Whiskey Impact
areas, units on ranges adjacent to the Zulu and Whiskey Impact Areas shall
mark their forward position with an Infrared (IR) Strobe, IR chem-light, or a
visible light source. Once air assets know of, and have positively identified
the forward position, LONGRIFLE may contact the unit to secure the IR
light source.
6002. PROCEDURES FOR RANGE CHECK-IN/OUT
1. Briefs. The RSO (including FACs) must participate in a “Hot Brief” with
LONGRIFLE via radio on frequencies: UHF 301.9, 249.9, 255.2; VHF 123.2; FM
