Several of the colonels widely expected to appear on the resulting promotion list, which has not yet been released, are considered unconventional thinkers who were effective in the Iraq campaign, in many cases because they embraced a counterinsurgency doctrine that Petraeus helped craft, the officials said.

They include Special Forces Col. Ken Tovo, a veteran of multiple Iraq tours who recently led a Special Operations task force there; Col. H.R. McMaster, a senior Petraeus adviser known for leading a successful counterinsurgency effort in the Iraqi city of Tall Afar, and Col. Sean MacFarland, who created a network of patrol bases in Ramadi that helped curb violence in the capital of Anbar Province, according to the officers.
