History
Jack Frost 1975–1979
The Jack Frost was composed of three exercises held in 1975, 1976 and 1979. The first of these was Jack Frost '75, an Alaskan Command-sponsored exercise. The second is Jack Frost '76, it has exercises sponsored by the United States Readiness Command.
This year, units from the 9th Infantry Division from Ft. Lewis included the 3/34FA and 2/47 Infantry deployed in the field to test cold weather operations. In 1976, a detachment of the 337th Army Security Agency Company provided electronic warfare training which included electronic countermeasures (ECM), electronic counter-countermeasures (ECCM), and communications security.
US Readiness Command learned that the nickname, Jack Frost, was prohibited by JCS publications. The command received approval for the name Brim Frost, and the final Jack Frost exercise ran in 1979.

Why this record matters
The phrase “united States military joint training exercise” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q5420037. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1975, 1979 and 1976.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
