Whakaotihia te rerenga e whai ake nei: I te ngahuru o te tau 1942, e rua nga roopu Raider taapiri i hangaia; ko te 3 Raiders i Samoa, na Lt. Col. Harry B. Liversedge i whakahau, me te 4 Raiders i Camp Pendleton, California, i whakahaua e Lt. Ko te Koronela James Roosevelt. Ko enei roopu i wehewehe i a raatau i roto i nga pakanga pakari i te taha o te 1st me te 2d Raiders i nga pakanga o te 1943 i te rohe o te Moana-a-Kiwa.
Ko ngā Moana o runga. I te 15 o Poutu-te-rangi 1943, i whakaritea nga roopu e wha hei 1st Marine Raider Regiment i Espiritu Santo, me Liversedge hei rangatira me Carlson hei rangatira whakahaere. I tohua a Lt. Col. Alan Shapley hei rangatira mo te 2nd Raiders i te wiki i muri mai ka hoki wawe mai ki te whakahaere paerewa.
