The CSH is capable of providing definitive care for many cases. Current medical doctrine does not encourage wounded soldiers, if they are not expected to quickly return to operational status, to stay in the combat zone. This is a pragmatic decision as the resources are usually available to bring them home quickly. Military aircraft constantly fly into a theater of operations loaded with equipment and supplies, but often lack a back cargo. Given that adequate "airlift" is usually present, it is easy to evacuate wounded promptly. For this reason the CSH bed capacity is not as heavily used as in past conflicts.
