On Veterans Day there have been ceremonies held across the US to honur the dead and wounded of its wars. Thousands of people have paid tribute to members of the US armed forces. But with the US still at war, there's particular focus on veterans of the Iraq and Afghanistan wars - who now number almost one and a half million men and women. President-elect Barack Obama has pledged to improve the government's care for veterans. But as Al Jazeera's Tom Ackerman reports, it won't come cheap.
