<1> Select Using Threat Severity Level. Select the next structure to execute using
the ballistic threat severity level. For a severity level of low, proceed to
<2>. For a severity of medium, proceed to <3>. For a severity of high,
proceed to <4>. For a severity of very high, proceed to <5>.
<2> Get Cross-Section Certified for Low Threat Severity Level. ind the appropriate
F
cross-section type inTable 8. From the table, select the cross-section of
that type which most closely resembles the existing cross-section. Proceed to
<6>.
<3> Get Cross-Section Certified for Medium Threat Severity Level. ind the
F
appropriate cross-section type in able 9. From the table, select the cross-
T
section of that type which most closely resembles the existing cross-section.
Proceed to <6>.
<4> Get Cross-Section Certified for High Threat Severity Level. ind the appropriate
F
cross-section type inTable 10. From the table, select the cross-section
which most closely resembles the existing cross-section. Proceed to <6>.
<5> Get Cross-Section Certified for Very High Threat Severity Level. ind the
F
appropriate cross-section type in able 11. From the table, select the cross-
T
section which most closely resembles the existing cross-section. Proceed to
