 Depending on the severity of the injury, the soldiers may then be transferred to a level-II facility, which consists of a forward surgical team, for additional stabilization.Depending on the logistics of the locality, the injured soldiers may transfer between these facilities several times before finally being taken to a major hospital within the combat zone (level III).Generally after 1–3 days, when the patients are stabilized, they are transferred by air to a regional facility (level IV) for additional treatment.
