Pakistani political commentator AyazAmir says the suspects are low-ranking officers and enlisted men, and that the president's still has strong support from senior military staff.
Amir says some junior officers probably share these views, there is very little chance of an organized coup against the president.
Amir notes that General Ayub Khan, Pakistan's military ruler during the 1950s and 60s, also stepped down from his army post late in his career but was able to remain in control of the country.
