From testimony from an Egyptian military officer, published by Jack Shenker in the Guardian: Egyptian army officer's diary of military life in a revolution:
After Mubarak fell and the rule of Scaf (Supreme Council of the Armed Forces) began, the top brass moved quickly to secure the loyalty of all mid-level and junior officers. Whenever a big Friday street demonstration or rally in Tahrir Square took place we would all receive a bonus of between 250 and 500 Egyptian pounds (£26-52), whether or not we had anything to do with policing the protests.
It's ridiculous; at the height of the unrest reserve officer salaries doubled and everyone was getting huge bonuses all the time (an average of 2,400 pounds – £254 – for me in January and February). Most full-time officers didn't really care what was happening politically on the streets, they were just happy with the extra money. Occasionally though you'd hear guilty jokes about how we were the only people who were benefiting from the revolution and the Egyptian people had been screwed over.
Read the whole thing, it's very enlightening although not altogether surprising. This is how it ends:
But as the months went on, despite this ignorance and the generous bonus system, dissent against [Egypt's commander-in-chief and current head of Scaf, Field Marshal Mohamed Hussein] Tantawi has grown. Most of the mid-level officers now think of him as Mubarak's right-hand man, and they hate the fact that Scaf's violence has tarnished the army's image in the eyes of the public. Many still disapprove of the current protests because they feel it's not the right time, and also because they're resentful that others can go and demonstrate on the streets when they themselves do not have such freedom. But that attitude is beginning to change, especially as independent TV channels have been airing video clips of the recent violence and the brutality of the security forces is being openly discussed by people like [prominent media personalities] Yosri Fouda and Ibrahim Eissa. More and more mid-level officers are turning against Scaf, and against Tantawi."
