U.S.-trained Iraqi police and military forces will handle most of the security duties during nationwide voting in October and December, so the American military is likely to send only a few thousand extra troops to Iraq for that mission, a senior U.S. commander said Friday. Some officials had indicated recently that up to 20,000 extra U.S. troops might be needed during the voting. Lt. Gen. John Vines, commander of Multi-National Corps-Iraq, said he expected to need no more than 2,000 extra troops because there are thousands more Iraqi troops available than during last January's election. The Pentagon says Iraq has about 180,000 security forces now, compared to about 130,000 last January.
