The Travel Support Branch (TSB) serves as the Defense Travel System Tier II Help Desk / Lead Defense Travel Administrator (LDTA) and is the single focal point of DTS support for command ODTAs aboard Quantico, Marine Barracks 8th & I, and subordinate commands located worldwide.  TSB establishes and conducts training focused on each individual’s specific role in DTS, enabling the commander to utilize DTS to manage mission-essential temporary duty travel effectively.  We ensure sensitive information security, limiting each level of access to appointed personnel with appropriate training by closely monitoring and managing DTS permissions.
