Risk Impact Value (Numeric Value). This value represents an estimate of the conditions under which the
unit will operate and is an indicator of the severity of environmental degradation.

Risk Category
Extremely High (E)
Mission failure if hazardous incidents occur during mission. A frequent or likely probability of
catastrophic loss (IA or IB) or frequent probability of critical loss (IIA) occurs.
High (H)
Significantly degraded mission capabilities in terms of required mission standard or not
accomplishing all parts of the mission, not completing the mission to standard (if hazards occur
during mission). Occasional to seldom probability of catastrophic loss (IC or ID). A likely to
occasional probability of a critical loss occurring (IIB or IIC) with material and soldier system.
Frequent probability of marginal (IIIA) losses.
Moderate (M)
Expected degraded mission capabilities in terms of required mission standard. Will have reduced
mission capability (if hazards occur during mission). Unlikely probability of catastrophic loss (IE).
The probability of a critical loss occurring is seldom (IID). Marginal losses occur with a probability of
no more often than likely (IIIB or IIIC). Frequent probability of negligible (IVA) losses.
Low (L)
Expected losses have little or no impact on accomplishing the mission. The probability of critical
loss is unlikely (IIE), while that of marginal loss is no more often than seldom (IIIB through IIIE).
