Almost half of the first 1,000 to die have been either E-3s or E-4s. Almost half of the 1,000 were younger than 24.
Nearly three-fourths of the deaths have been Army.
Two-thirds of the deaths have been caused by enemy action or devices.
Reserves/Guardsman makes up 18 percent of the deaths.
More than 70 percent of those who have died were white. Despite fears that an all-volunteer force would end up putting minorities at greater risk than whites, the military death toll is distributed proportionately among America’s racial and ethnic groups.
