It depends on the issues and forces at stake. The communist revolution in Germany failed because the military, on the whole, remained with the establishment; whereas in Russia, this was not the case.
On the other hand, in the English and American Revolution there was a long, drawn-out civil warfare where both sides had a well equipped military.
And in Tianeman square, for a few days, it looked like it could go either way.
