 OAKLAND, Calif. — For supporters of the Occupy Wall Street movement, whose diffuse anger has been a defining and sometimes distracting characteristic, the wounding of an Iraq war veteran here has provided a powerful central rallying point. 
  
 The veteran, Scott Olsen, 24, was critically injured on Tuesday night when he was hit in the head with a projectile thrown or shot by law enforcement officers combating protesters trying to re-enter a downtown plaza that had been cleared of an encampment earlier in the day. Mr. Olsen, who served two tours of duty in Iraq as a Marine, suffered a fractured skull. 
  
 And while Mr. Olsen’s condition has since improved, his injury — and the oddity of a Marine who faced enemy fire only to be attacked at home — has prompted an outpouring of sympathy, as well as calls for solidarity among the scores of Occupy encampments around the nation. On Thursday night, camps in several major cities — including New York, Chicago and Philadelphia — were expected to participate in a vigil for Mr. Olsen, according to Iraq Veterans Against the War, of which he is a member. 
  
 “I think people would have been outraged even had this been a civilian,” said Jose Vasquez, the group’s executive director, “but the fact that he survived two tours of duty and then to have this happen to him, people are really upset about that.”

 Friends of Mr. Olsen — who worked in computer systems at a Bay Area technology company — said that he had eagerly joined the Occupy movement, heading to the San Francisco camp after work and sleeping on the streets in solidarity with the campers there. He was in Oakland on Tuesday to take part in the demonstration there. ||||| A soldier kneels with an American flag in front of a candle-lit memorial in support of Scott Olsen at City Hall in Oakland October 27, 2011.

 OAKLAND, Calif An Iraq war veteran badly wounded in clashes between protesters and police on the streets of Oakland was awake and lucid, hospital officials and family members said on Thursday. 
  
 Scott Olsen, a 24-year-old former U.S. Marine struck in the head during Wall Street protests on Tuesday night, had been upgraded from critical to fair condition overnight. 
  
 Olsen's injury has become a rallying cry for the Occupy Wall Street movement nationwide, and Oakland organizers said they would stage a general strike over what a spokeswoman called the "brutal and vicious" treatment of protesters, including the young Iraq war veteran. 
  
 At the downtown plaza where he was hurt, several hundred supporters turned out Thursday night for a candlelight vigil in which fellow activists from a group called Iraq War Veterans for Peace addressed the crowd. One drew loud cheers when he said the police chief or mayor should resign. 
  
 Olsen "responded with a very large smile" to a visit from his parents, Highland General Hospital spokesman Warren Lyons said at a late-afternoon press conference on Thursday. 
  
 "He's able to understand what's going on. He's able to write and hear, but has a little difficulty with his speech," Lyons said. 
  
 He said doctors had not operated on Olsen yet and were waiting to see if swelling in his brain eased. 
  
 Olsen's aunt, Kathy Pacconi, told Reuters in an email that her nephew was showing signs of improvement. 
  
 "I believe he knew his mom and dad were there, and tomorrow he'll be really happy to see his sister, Melissa, because they are really close. Hopefully, he'll start to improve with her visit," Pacconi said. 
  
 Occupy Oakland organizers said their strike, scheduled for next Wednesday, was intended to shut down the city. 
  
 'SHUT THE CITY DOWN' 
  
 "We mean nobody goes to work, nobody goes to school, we shut the city down," organizer Cat Brooks said. "The only thing they seem to care about is money and they don't understand that it's our money they need. We don't need them, they need us." 
  
 Spokeswomen for the city of Oakland and Mayor Jean Quan could not be reached for comment. 
  
 Brooks said a general strike was a "natural progression" following a crackdown by the city of Oakland early on Tuesday morning in which protesters were evicted from a plaza near city hall and 85 people were arrested. 
  
 Protesters sought to retake that plaza on Tuesday night and were repeatedly driven back by police using stun grenades and tear gas. It was during one of those clashes that protesters say Olsen was struck in the head by a tear gas canister fired by police. 
  
 The hospital has confirmed Olsen was hurt during the protest, but could not say how he was wounded. Acting Oakland Police Chief Howard Jordan had told a news conference his department was investigating the incident. 
  
 He said police had fired tear gas and bean-bag projectiles when protesters defied orders to disperse. He also said that some demonstrators had pelted police with rocks and bottles. 
  
 Olsen is believed to be the most seriously wounded person yet in confrontations between police and activists since Occupy Wall Street protests began last month in New York. 
  
 News of his injury ignited a furor among supporters of the protests. Activists in Oakland and elsewhere took to Twitter and other social media urging demonstrators back into the streets en masse. 
  
 More than 1,000 protesters moved onto the streets of Oakland again on Wednesday night as police largely kept their distance. 
  
 At Thursday's vigil, Emily Yates, an Army veteran of two tours in Iraq, urged restraint by police and protesters. 
  
 "The police claim they were just doing their job. It's all of our job to think before we throw anything at each other," she said. 
  
 Steve Morse, 65, a Vietnam War veteran, drew a hearty cheer when he called for the resignation of either Police Chief Jordan or Mayor Quan, both widely criticized as having bungled the city's response to the Occupy Oakland movement. 
  
 The crowd roared back with gusto when a woman from the crowd later yelled out, "Where's our mayor?" 
  
 Organizers said Quan had been invited in an open letter to address the vigil, but she was not present. 
  
 Friends say Olsen had been active in several anti-war veterans groups and had joined Oakland protesters in a gesture of solidarity after learning of the police crackdown there. 
  
 Keith Shannon, 24, who said he served with Olsen in Iraq, told Reuters his friend suffered a two-inch skull fracture. 
  
 Olsen served two tours in Iraq from 2006 to 2010 with the 3rd battalion, 4th Marine Regiment, Shannon said, adding that he and Olsen deployed together and were assigned to a tactical communications unit.

 "He was standing perfectly still, provoking no one," said Raleigh Latham, an Oakland filmmaker shooting footage of the confrontation between police and hundreds of protesters at 14th Street and Broadway. "If something didn't hit him directly in the face, then it went off close to his head and knocked him down." 
  
 The something was a projectile that apparently came from police lines, fractured Olsen's skull and put him in Highland General Hospital. Doctors upgraded his condition Thursday from critical to fair, and said they expect him to make a full recovery. 
  
 His parents flew in from Wisconsin and spent Thursday at his bedside. When they arrived, Olsen "just blossomed," said Highland's chief of surgery, Dr. Alden Harken. 
  
 Olsen's injury added to the national attention focused on Occupy Oakland in the aftermath of the repeated police tear-gassing of protesters Tuesday. In Las Vegas, protesters projected a photo of the Marine in uniform onto the corrugated-metal side of a building at their camp, the Associated Press reported. Vigils for Olsen were planned at Occupy sites in other cities. 
  
 Mayor's visit 
  
 Mayor Jean Quan visited Olsen in the hospital, told him she was sorry for what happened and promised an investigation, said Highland spokesman Vintage Foster. 
  
 Olsen, a Daly City resident and member of Iraq Veterans Against the War, fell to the ground after police lobbed or fired an object - possibly a tear gas canister - at a group of protesters. 
  
 While Olsen lay wounded in the street, other protesters rushed to his aid. Video footage appears to show an officer tossing another canister toward the group helping him. 
  
 One protester can be heard screaming "What the f-" at police as the device emits a loud bang, while a demonstrator angrily pounds his sign on the street. The group eventually carried Olsen away. 
  
 Interim Police Chief Howard Jordan called the incident "unfortunate." 
  
 "I wish that it didn't happen," Jordan said. "Our goal, obviously, is not to cause injury to anyone. ... We regret that this injury happened." 
  
 Officers from 18 law enforcement agencies were on the streets of Oakland Tuesday night, and authorities said they are trying to determine which officers were involved in Olsen's injury. Quan said officers from outside agencies had been told they had to abide by Oakland police procedures. 
  
 Olsen joined the Marines in 2006, served two tours in Iraq and was discharged in 2010, according to Iraq Veterans Against the War. Now a systems administrator at San Francisco software firm OPSWAT Inc., he had spent most nights during the last few weeks at the Occupy SF camp, said his roommate, Keith Shannon. 
  
 "He'd leave work, head there, sleep there and go to work the next day," Shannon said. "We were really against the fact that the banks and corporations were not held accountable for what they did." 
  
 BART to Oakland 
  
 When Olsen heard that protesters at Occupy Oakland were asking for support, he took BART to Oakland and joined in the protest, Shannon said. 
  
 Olsen knew he might be arrested, but didn't have any idea the demonstration would get as violent as it did, Shannon said. 
  
 Harken said Olsen had suffered a 2- to 3-inch fracture on the left side of his skull. He is able to write and move, but is having trouble speaking, Harken said. 
  
 Olsen has a bruise on his brain that is causing swelling, but he should recover fully without needing surgery, Harken said. 
  
 Olsen was dropped off at the hospital by people in a private car and was unconscious for 12 hours, Harken said. He is unaware of the global interest in his condition. 
  
 "He wouldn't be able to comprehend it," the doctor said.

Scott Olsen, the 24-year-old Iraq war veteran who suffered a fractured skull when police raided the Occupy Oakland camp on Tuesday, is awake and lucid, and doctors have upgraded his condition from critical to fair, Reuters reports. “He’s able to understand what’s going on,” a hospital spokesman said. “He’s able to write and hear, but has a little difficulty with his speech.” Olsen’s parents flew in from Wisconsin yesterday to see him, and he “responded with a very large smile” when he saw them. Olsen has a large bruise on his brain, but chief of surgery Alden Harken tells the San Francisco Chronicle that he should recover without surgery. As "We are all Scott Olsen" becomes a rallying cry, candlelight vigils were held for him in New York, Chicago, Philadelphia, and, of course, Oakland last night, the New York Times reports. Oakland’s mayor has also visited him, promising an investigation. But Olsen is unaware of his newfound fame. “He wouldn’t be able to comprehend it,” Harken says.
