Tuhia he haere tonu mo tenei whitianga - I te 24 o Mei 1920, i whakaaetia e te Hekeretari o te Pakanga a Baker te whakawhānui i te Mahere Pakanga White ki te whakatutuki i nga whakaekenga o te kaainga, ahakoa te kaupapa tōrangapū o te hunga whakaeke. Ko te kawenga mo te hanganga o te mahere i wehewehea i waenga i te Tari Pakanga me te rohe o te 9 corps i hangaia e te ope taua. Ko nga whakahau o tawahi i nga rohe o Amerika penei i a Hawaii me te Canal Panama
i whakawhiwhia ki te whakawhanake i ā rātou ake mahere. Ahakoa i whakawhanakehia e ia rohe o te ope he mahere motuhake mo te kaha o taua rohe o te ope, i mau tonu te mana whakahaere o te kaupapa ki te Tari Mahere Pakanga.
