not entirely true :
Nautilus departed
Hawaiian waters for her second war patrol, a special troop transport mission of three weeks duration, 8 August. Sailing with submarine
Argonaut and carrying the
Second Raider Battalion under Lieutenant Colonel
Evans F. Carlson (the
Marine Raiders, or "Carlson's Raiders") she arrived off
Makin Atoll on 16 August to stage a
raid to divert Japanese attention from the
Solomon Islands.
But anyway i too noticed that they wore USMC belt buckles but never really computed how strange that was... Possibly they swiped them from Marine stores while at port for souvineers lol
