On tonight's PBS special When Parents are Deployed, Elmo gets some sad news - his father Louie is leaving for parts unknown. While no specific branch of the military is mentioned, it's clear that Louie is being shipped off to either Iraq or another war-torn country. Elmo, the army brat, is in for some heartbreak. And, from the sound of the New York Times' review of the special, so are we. Elmo's segments are played between interviews with actual soldiers and their often traumatized children.
