This article puts a number on it and seems a lot more comprehensive.

“Boykin referred to recent reports that Obama has purged some 197 officers in the past five years.”
Have you tried to discover who those 197 people might be. That turns out to be very hard to do. Approximately 157 of them turn out to be Navy Lt. Commanders who are being released because of a reduction of Navy strength. A number of the others are mid grade officers who committed some infraction or place their ships in ad hoc dry dock by driving them onto reefs. Boiling it down, you can actually come up with the names of 9 general/flag officers who were sacked, mostly for personal conduct issues.
See my comment, still standing by it:

0bama is replacing and has replaced the commanders of our nuclear submarines with those who will not return fire.
Remember, 0bama specifically said that a nuclear weapon could go off here and would not be avenged. I am certain there have been attempts to put him at his word.
