It could be considered rash to presume to lecture the former Deputy
Battle Staff Commander, New York NORAD Air Defense Sector, on managing
nukes safely. I never lost a one.
Stop there, or go and google the warshot yields of GENIE, Nike-Hercules
(improved) and BOMARC.

And note that after military service, the same individual pursued a
telecoms IS/IT career from Northrop-Page (1968) thru Cable & Wireless
(until 1994) - and still does - Conducive Group (Asia) Limited (1994 to
date).

Horsepuckey. Tell it to the Royal Marines.
I was responsible for the V.36 (not V.35) routing and billing interface
software to an AXE-10 International gateway switch in London that was
odd-man-out in UK's largely 'anything-BUT Ericcson' environment. GSM,
some, fixed-line and international, NOT.
A Senior Ericsson exec once apologized 'on behalf of all hundred
thousand Ericsson employees' for that particularly unfortunate POS.
Erlang is largely concept, and near-as-dammit uniquely Ericsson.
What are you doing now? Googling for off-the-wall trivia to throw out
here so as to delay developers?

Google AN/FSQ-7 and AN/GSA-51 and their fallback modes while you are
thinking 'new to...'
Doubt you were born yet.
When you find yourself at the bottom of a hole, good advice is 'stop
digging'.
