text_A: On the night of 13 May 1978, Denard and 42 other mercenaries landed on Grande Comore island, annihilated the well trained but badly commanded Moissy, all of who had military experience, and by the morning the Comoros was theirs. President Soilih was high on marijuana and naked in his bed together with three nude teenage schoolgirls watching a pornographic film, when Denard kicked in the door to his room to inform him that he was no longer president. Soilih was later taken out and shot with the official excuse being that he was "shot while trying to escape". The new president of the Comoros, Ahmed Abdallah, was a puppet leader and the real ruler of the Comoros was Colonel Denard, who brought the Comoros back into "Françafrique".
text_B: Just prior to joining the Moissy, would members of the Moissy have to pay full price while shopping at a store that offered a discount for veterans?
NO.
