Flash have a limited number of write, not something you want to deal
with in a desert year long operation.
(military helicopters have such a long live time, mechanical maintenance
is ok on field, but electronic maintenance is always long, expensive &
tricky (i.e. not for the sergent)

Usually a little explosive if all they need... as long as it is not
triggered by the EMP. If the information is really sensitive.
Usually it is not: the main target (or secondary ones) is just
coordinates for that mission. And nowadays, everyone has maps.
The Friend-or-Foe identifiers will be changed by the next day/hour, no
problem either.
