It’s hard to predict exactly, but it’s estimated that over the next decade, there will be about 1.6 million veterans returning from active service.
Since 2001, 2.5 million service members have been deployed in Iraq or Afghanistan—Vets who served since Sept 2001 are called “Gulf War Era II” vets.
Among Gulf War II vets, more than a third of these were deployed more than once and nearly 400,000 were deployed three or more times.
