That picture was not taken at Tarawa. There were no LVT(A)-1s at Tarawa. There were only LVT-1s and LVT-2s at Tarawa. There is also no seawall in the picture. Tarawa had a seawall on red beach where the main landing took place. There is also an LCT(5)in the picture. I don't believe LCTs were used at Tarawa. LCT 346 was built by Decatur Iron and Steel and commissioned in October 1942.
