1-83. The goal of all sustainment training is for the detachment to be able to execute a full mission profile. To that end, the detachment must conduct a semiannual operational mission exercise that puts as many of their mission ready skills to use at one time as can be realistically coordinated. This exercise can be conducted in conjunction with other training requirements mentioned above. Multiple delivery methods should be used, coupled with a surface swim, an underwater navigation team swim, or both. An example would be an airborne or airmobile OTH insertion with CRRCs with an offshore navigation to a drop-off point. This method would be followed by a turtle-back swim to a point 1,500 meters offshore, a closed-circuit underwater team compass swim with equipment to the BLS, and an over-the-beach infiltration. Following a UW or DA mission, the team would execute an over-the-beach exfiltration and some form of marine extraction. It may of course be impossible to include all of these phases in one tactical exercise. However, multiple phases must be conducted in each exercise. Realistic training challenges the detachment to excel and gives the commander an effective tool to assess mission capabilities.
