CBS Military Analyst retired US Army Col. Jeff McCausland joins Megan Lynch for an in-studio visit. He shares how he was recruited to be the CBS analyst while he was teaching at West Point, nearly 25 years ago. He talks about how his role has shifted from leading troops to sharing with the public what the military is up to. 'I'm not a pundit' says McCausland, 'I'm an analyst,' using the baseball reference of an umpire, 'calling balls-and-strikes.'
