Iraq - the Iranian Military Drain?

Ynet News carries this report:

Three weeks ago the Iranian armed forces command in Teheran lost contact with a senior officer who had been serving in Iraq with the al-Quds unit of the Iranian Revolutionary Guards Corps, according to a senior Iranian official cited in the Wednesday edition of the London-based Arabic daily al-Sharq al-Awsat.

The Iranian source said that it is still unclear why contact with the officer, Colonel Amir Muhammad Shirazi, was lost. "It is possible that the American forces in Iraq arrested him along with a group of 13 Iranian military and intelligence officials," he said, adding that this is just one of the scenarios being investigated by Tehran.
(…)
Al-Sharq al-Awsat reported that a Tehran military court sentenced to death a colonel in Iranian military intelligence who recently returned from service in Iraq. The officer was accused of collaborating with American forces and providing them with details on the deployment and activities of the al-Quds unit and Iranian military intelligence operatives. He was also accused of providing the Americans with classified documents, photographs and maps related to Iran's nuclear program and armed forces.

The newspaper reported that over the past three years, dozens of members of Iran's Revolutionary Guards and military intelligence units have defected to the American forces in Iraq.

Sounds like staying the course has had a few fringe benefits after all.
