MD 21220-2896.
TM 5-853-1 defines threats to military assets
including the forced entry tactic in terms of
weapons, tools, and explosives. The threat to an
asset may be developed using the threat analysis
procedure described in TM 5-853-1. TM 5-853-2 and
TM 5-853-3 contain guidance on design and protective
measures to resist forced entry and other tactics.
To be effective, a forced entry resistant component
must be part of a forced entry resistant
construction envelope that protects and asset.
Refer to appendix C of TM 5-853-2 for a table of
components and construction elements that are rated
against various threat severity levels of the forced
entry tactic. If a designer chooses to design
components for shop fabrication, the materials
should be specified in appropriate sections
including Section 05500A, MISCELLANEOUS METALS.
At the time of preparation of this specification,
manufacturers had not tested vehicle doors to the
forced entry test standards covered herein. The
designer may specify oversized swinging doors or
specify a door for vehicle entry to meet a forced
entry test standard as an alternate bid item, or
under a separate bid request doors to be tested in
accordance with the required test standard. If the
latter is chosen, allow long lead time for the
manufacturer to design, test, and receive approval
of the door.
**************************************************************************
Each type of forced entry resistant component shall be the standard product
of a manufacturer regularly engaged in the manufacture of such products and
shall duplicate items that have been tested and approved in accordance with
the forced entry test standard specified in paragraph COMPONENT TEST
REQUIREMENTS. Manufacturer's descriptive data, installation instructions,
and certificate and test report showing compliance with the specified
forced entry test standard as specified in paragraph COMPONENT TEST
REQUIREMENTS shall be submitted for all components. [Following approval of
manufacturer's descriptive data, a schedule listing the items and
components to be furnished shall be submitted.] [Drawings shall be
submitted.] Manufacturer's certificate shall be submitted indicating that
compliance with the installation instructions [and drawings] will provide
the specified degree of forced entry resistance.

COMPONENT TEST REQUIREMENTS
**************************************************************************
NOTE: The project forced entry threat must be
identified before selection of test standard. The
designer will then select the forced entry testing
standard that most represents the threat, using
Table I. The designer will then indicate the
applicable test standard in paragraph COMPONENT TEST
REQUIREMENTS or on the drawings in door, window, or
other component schedule.
