In the animated film "Aim for the Top: GunBuster" created by the same director Anno, he copied several lines from Okamoto's film, "The Battle of Okinawa" (1971), such as, 'there are too many ships that I can't see the sea,' and '70% is occupied by ships and 30% by the sea,' and he imitated a subtitle giving the phrase 'XX thousand bombshell shots/ xx thousand rocket bombs,' as an homage, and when "The Battle of Okinawa" was released on Laserdisc (LD), Anno also wrote liner notes.
同じ庵野の監督作『トップをねらえ』では、岡本の『激動の昭和史沖縄決戦』（1971年）における「船が多すぎて海が見えない」、「船が七分に海が三分」などのセリフや、「砲弾○万○千発/ロケット弾○万○千発」のテロップをオマージュとして模倣しており、『沖縄決戦』がLD化された際には庵野がライナーノートを書いている。
