In a collective application, 312 generals -- among them the heads of the land and air forces, the navy and paramilitary forces -- demanded 624 billion Turkish lira (422,000 dollars, 360,000 euros) from Asim Yenihaber and the Vakit newspaper for which he writes.
"No one has the right to comment in such a degrading and belittling way about the high-ranking commanders of the Turkish armed forces," the plaintiffs said.
According to excerpts from the August 25 article quoted in the application, Yenihaber wrote: "There is nothing to show that they are generals apart from the stars on their shoulders."
He also allegedly said: "There is no place for them neither in the army, nor in this country ... They will be powerless in the face of a real enemy, they will be swept away."
Turkey's Islamists and the powerful army, the self-declared guardians of the Muslim nation's secular system, have been arch-enemies for decades.
The military, which sees political Islam as a major threat to Turkey's stability, has restlessly cracked down on Islamist movements and in 1997 ousted from power the country's first Islamist-led government.
