Go-Bag is a bag that all NCIS Special Agents have with them and which is packed with essential items such as a toothbrush or clean underwater. The bag is often used in the event that an NCIS Special Agent assigned to Washington D.C. has to make an emergency trip to Los Angeles and stay overnight. The NCIS Major Case Response Team led by NCIS Special Agent Leroy Jethro Gibbs all carry go-bags with them.
