An amphibious task group combines combat power with its own sustainment

The British amphibious formation combines troop delivery with the support needed to operate as a group. HMS Ocean appears alongside either Albion or Bulwark; the identification of that ship in the photograph is uncertain. Other ships include a Fort-class supply ship, Wave-class tankers, a landing ship logistics vessel, and an oceanographic ship. The landing ship logistics vessel is tentatively identified as one of the older Round Table ships, probably Sir Bedivere. A Type 42 destroyer and Type 23 frigate add escort and combat power. Together these ships can move troops, sustain them, defend the formation, and support helicopter operations. Each task group is theoretically self-sufficient, carrying the supporting capabilities needed for its mission within the larger task force. Its scale is roughly comparable to a brigade or division, though concentrated naval firepower makes any direct army analogy imperfect.
