What Will the Army Do?

I've been watching a live CNN feed from the corniche, where an Army APC (something in the Russian BRDM family I think) is being surrounded by demonstrators who seem to be cheering the Army. The traditional respect Egyptians accord the Army seems to be in evidence. But whereas the Central Security Forces were cracking down hard, the Army seems to be fraternizing. The Army high command is docile, but the Army has always been the ultimate guarantor of the regime, and if the senior officer corps ever feels that the only way to save the system is to change the leadership, they have the ability to do it.
