 MIL-HDBK-1013/12
<1> Required Level of Protection? Use the level of protection to determine which structure to go to. For a
low level of protection, proceed to <2>. For a medium level of protection, proceed to <3>.
<2> Enter Protective Measures for Low Level of Protection. Refer to Table 13 for protective measures. In
the laminated glass row of the Cross-Section Selection worksheet (see Appendix B for all worksheets),
enter the cross-section recommended in Table 13 into column (e). On the Frame Selection worksheet,
enter the word "standard" into column (e) for all frame properties. On the Wall Selection worksheet, enter
the word "standard" into column (e) for all wall thicknesses. Return to Figure 8.
<3> Use Threat Severity Level to Select Analysis. This is a multiple choice type selection. Follow the path
that corresponds to the appropriate threat severity level: low, medium or high. If the threat severity level is
low, proceed to <4>. If the level is medium, proceed to <8>. If the level is high or very high, proceed to
<12>.
<4> Get Minimum Glazing Specifications for a Low Threat Severity Level. Refer to Table 14 for the
minimum glazing specifications for low threat severity level requirements. Enter these specifications in
column (e) of the Cross-Section Selection worksheet. Proceed to <5>.
<5> Get Minimum Frame Specifications for Low Threat Severity Level. Refer to Table 15 for minimum
frame specifications that meet low threat severity level requirements. Enter these specifications in column
(e) of the Frame Selection worksheet. Proceed to <6>.
<6> Get Minimum Anchorage Specifications for Low Threat Severity Level. Refer to Table 16, Table 17,
Table 18, and Table 19 for minimum anchorage specifications that meet low threat severity level
requirements. Enter these specifications in column (e) of the Anchorage Selection worksheet. Proceed to
<7>.
<7> Get Minimum Wall Specifications for Low Threat Severity Level.
<8> Table 20 provides the minimum wall thicknesses that meet low threat severity level requirements. Enter
these specifications in column (e) of the Wall Selection worksheet. This step completes the forced entry
attack analysis for selection application procedure. Return to Figure 8.
<9> Get Minimum Glazing Specifications for Medium Level Security. Refer to Table 21 for minimum
glazing specifications that meet medium threat severity level requirements. Enter these specifications in
column (e) of the Cross-section Selection worksheet. Proceed to <9>.
<10> Get Minimum Frame Specifications for Medium Level Security. Refer to Table 22 for minimum frame
specifications that meet medium threat severity level requirements. Enter these specifications in column
(e) of the Frame Selection worksheet. Proceed to <10>.
<11> Get Minimum Anchorage Specifications for Medium Level Security. Refer to Table 23, Table 24,
Table 25, and Table 26 for minimum anchorage specifications that meet medium threat severity level
requirements. Enter these specifications in column (e) of the Anchorage Selection worksheet. Proceed to
<11>.
<12> Get Minimum Wall Specifications for Medium Level Security. Table 27 provides minimum wall
thicknesses that meet medium threat severity level requirements. Enter these specifications in column (e)
of the Wall Selection worksheet. This completes the forced entry attack analysis for selection application
procedure. Return to Figure 8.
<13> Mark Glazing Does Not Meet Design Requirements. Glazing will not protect against a high or very high
level forced entry attack. Requirements must be changed to use glazing in this application. Mark the "No"
checkbox in response to the question "Does Glazing Cross-Section Meet Design Requirements?" at the
bottom of the Cross-Section Selection Worksheet. This completes the forced entry attack for selection
application procedure. Return to Figure 8.
