https://en.m.wikipedia.org/wiki/Hannibal_Directive
Regarding the name:
Israeli officials insisted that the directive’s name was a random computer-generated designation, however, Hannibal, the Carthaginian general, is said to have preferred suicide by poison rather than being taken prisoner by his Roman enemies.
The “m.” is probably [minim](https://en.m.wikipedia.org/wiki/Minim_(unit\) ) and “gr.” will be [grain](https://en.m.wikipedia.org/wiki/Grain_(mass\) )
