Large exercise located South of Nago possibly near Koki Okinawa . The Battalion Landing Team ( BLT) used various amphibious water craft. Mechanized Landing Craft/LCM "Mikes Boats" and LCVP "HIGGINS" boat meeting at assembly point after landing 3/3 Marines. The LCVP would hold 36 personnel and whatever APA or AKA ships you were on, once in the water the LCVP's seemingly would circle for hours until everyone was ready. The only problem bobbing up and down for that long, someone would get sea sick, once one started....Well you can take it from there,
