Two scales of Severity
The Severity section shows levels I to V, but the Risk level (P*S) and (D) section has Severity levels I to VI. This is not wrong, because the article says that other classifications are possible, but maybe we should be consistent within our article. --Heron (talk) 15:54, 1 February 2019 (UTC)
 * Looking at the latest version of the DoD standard cited in the article (MIL-STD-882E, issued 2012), there are only four severity categories (1 - Catastrophic, 2 - Critical, 3 - Marginal, 4 - Negligible), which are also inverted from the scale in that section. For easy reference, this is what the MIL-STD-882E version of the table looks like:


 * {| class="wikitable" style="text-align: center;"

! Probability / Severity --> !! Catastrophic (1) !! Critical (2) !! Marginal (3) !! Negligible (4)
 * Frequent (A) || High || High || Serious || Medium
 * Probable (B) || High || High || Serious || Medium
 * Occasional (C) || High || Serious || Medium || Low
 * Remote (D) || Serious || Medium || Medium || Low
 * Improbable (E) || Medium || Medium || Medium || Low
 * Eliminated (F)
 * colspan="4" | Eliminated
 * }
 * Improbable (E) || Medium || Medium || Medium || Low
 * Eliminated (F)
 * colspan="4" | Eliminated
 * }
 * colspan="4" | Eliminated
 * }


 * Really, risk assessment tables like this are fairly common nowadays (and especially familiar to most users of health & safety risk assessments), so can be constructed in whatever way makes most sense to what is being explained. And to be honest, I feel like the article could do with a significant overhaul, as a lot of the material is probably more appropriate at somewhere like Wikibooks. — Sasuke Sarutobi (push to talk) 17:31, 1 February 2019 (UTC)
