There's the VVAW, VFP (Veterans for Peace) which includes a lot of VVAW members, and the IVAW (some crossover there as well, and I think they might still be technically part of VFP, at least fundingwise, on paper.)
All three groups work together on things like

SEATTLE -- Ricky Clousing, a Sergeant in the U.S. Army, and a veteran of the Iraq War who has been AWOL for a year announced today at the Veterans for Peace convention in Seattle that he will turn himself in later today at the gates of Fort Lewis and face whatever punishment the military chooses to impose.
... Speaking immediately before Clousing was a conscientious objector to the Iraq War named Joshua Casteel who had met Clousing in interrogator school, where, he said, "they don't tell you that you'll have to strip men naked, wet them, and stand them in front of an air conditioner because you're trying to induce hypothermia. They don't tell you you'll be instructed to use the blunt edge of an axe to soften someone up for questioning. They don't tell you that Rumsfeld will deny using dogs just four days after you've been instructed to use them."
Other speakers supporting Clousing included:
--Kelly Dougherty, Co-Founder of Iraq Veterans Against the War, who said that Mark Wilkerson, 22, from Colorado was denied conscientious objector status, went AWOL, and is now about to turn himself in as well.
--Camilio Mejia of IVAW and VFP, who served nine months in military jail for resisting this war. "Ricky will be a free man even if he goes to jail," Mejia said.
--Hart Viges, an Iraq War vet who said that he joined up after 9-11 thinking there was an enemy to go after, but that he had a change of heart and became a conscientious objector.
--Michael Wong, who went AWOL during the Vietnam War and is featured in the film "Sir, No Sir." Wong said that he and the many other war resisters featured in that film are all now doing well with excellent careers. It is a lie, he said, when the military tells you that refusing to fight will ruin your life. "Ricky," he said, "is beginning a lifetime of service to community, nation, and world."
--Judy Linehan of Military Families Speak Out, whose son was deployed to Iraq. She said, "These resisters that are coming forward with enormous courage are our leaders."
