This appendix describes the format of orders and plans used
by chemical units to issue their instructions. It also describes
the annexes used by chemical staffs to transmit NBC defense instructions.
Warning orders are used to notify subordinate units of upcoming
operations or missions. The warning order may be an oral or written
message. There is no format for warning orders; however, it should
contain much of the following--
Chemical units will issue operation orders and plans using
the five-paragraph combat order format.
Task Organization. This
portion lists supporting chemical units under the proper control
headquarters. The command or support relationship for each chemical
unit is provided.
a. Enemy forces. Provides
information on the composition, location, and strength of opposing
forces. Concentrates on the enemy capabilities of value to the
b. Friendly forces. Provides
information on higher, adjacent, and supporting chemical units.
c. Attachments and detachments.
Lists attached and detached units not shown in the
2. Mission. The
mission of the supporting chemical elements is clearly stated,
including who, what, when, where, and why.
Intent. A brief
paragraph written by the commander that states his vision of the
operation, describes the purpose, visualizes the end state, and
illustrates how the operation will facilitate future operations.
a.Concept of the operation.
Clearly states the commander's plan for chemical support.
Informs and visualizes the commander's concept. It must be brief
and provide sufficient detail to ensure understanding of the commander's
intent and purpose. It should specify the general priority of
support and the tasks allocated to subordinate units.
b. Subsequent subparagraphs list supporting chemical units
numerically. Give specific responsibilities and identify tasks
to be performed by each unit.
c. The final subparagraph, "Coordinating Instructions,
" details coordination and control applicable to two or more
elements of the command.
4. Service Support. A
statement of combat service support instructions and arrangements
for chemical units. It addresses the materials necessary for decon
and smoke operations.
5. Command and Signal.
command post locations for supported units and chemical units.
It designates the succession of chemical staff responsibility
and alternate chemical headquarters.
instructions for coordinating and establishing communications
by different means. The signal operating instructions in effect
at the time are listed. Backup means are provided to reestablish
communications in case of radio failure.
The chemical commander will publish fragmentary orders in
fast-paced combat situations. Fragmentary orders are pertinent
extracts that provide specific instructions to subordinate commanders
or timely changes to existing orders. Fragmentary orders do not
have a specified format. However, the five-paragraph combat order
is normally used. It includes only necessary elements changed
from the original order. The fragmentary order may be issued orally.
In general, the fragmentary order--
- Is addressed to each action commander.
- Is addressed to higher and adjacent units for information,
- Refers to a previous order, if applicable.
- Includes changes in task organization, situation, and mission,
- Clearly provides brief and specific instructions.
Chemical support/NBC defense annexes are prepared by chemical
staffs to issue instructions to subordinate units concerning NBC
defense measures and responsibilities. Additionally, subordinate/supporting
chemical units may be given missions or taskings in this annex
instead of the basic order/plan. The format for this annex is
ANNEX_____(CHEMICAL SUPPORT/NBC DEFENSE) TO OPORD/OPLAN______
Time Zone Used Throughout the Order/Plan:______
1. SITUATION. Items of information affecting NBC defense not
included in paragraph 1 of the OPLAN/OPORD or that need further

brief statement of the NBC defense operation to be carried out,
to include subordinate/supporting chemical unit tasks/missions
b. NBC Defense Tasks to Subordinate and Supporting Units.

Matrix-type orders use an execution matrix to convey combat
instructions. They are designed to assist the commander and staff
to develop an order in a short period. Execution matrices can
be used by both chemical unit commanders and chemical staffs.
