Thursday's shootings in Chattanooga, Tennessee, which left four Marines dead and one sailor wounded, are part of a string attacks — some successful and others thwarted — against military recruiting stations in recent years.

"Recruiting offices have been kind of on the leading edge of targets simply because they are both ubiquitous and they're vulnerable," said Brian Michael Jenkins, senior adviser to the president of the RAND Corporation.
