 MIL-HDBK-1013/12
5.4.1
Required Information. The following information is
required for a cross-section ballistic resistant thicknesses
procedure:
a) Ballistic Tactic Design Basis Threat (low, medium,
high, or very high). This information is determined
using Appendix D and is recorded on the Glazing
System Design Criteria Summary worksheet.
b) Cross-section type. Refer to Section 2 for
descriptions of cross-section types.
c) Worksheets (see Appendix B):
1) Cross-Section Evaluation (CSE)
