Tuhia he tomokanga mō tēnei wāhanga - I muri i tana hokinga ki Ahitereiria, i tohua a Wilton hei Pirihimana e tiaki ana i te Whakahaere i te Tumuaki o te Rāwhiti, ko tana tūranga whakahaere tuatahi. I te marama o Noema 1955 i tukuna ia ki te Kaiwhakahaere Matua i te AHQ, i reira ia i te kawenga mo te matauranga, nga mahi me nga mahere, me te whai waahi ki nga whakaritenga a Ahitereiria mo nga whakangungu SEATO. I whakatairangahia ia ki te rangatira nui i te 24 o Poutu-te-rangi 1957, a ka riro ia hei Kaihauturu o te Royal Military College, Duntroon. Ahakoa kaore i tino whakapono, i whakaarohia e Wilton ko ia te kawenga mo te whanaketanga wairua me te whanaketanga o nga taiohi taiohi; i whai waahi ia ki te haere ki te huihuinga karakia i nga wa katoa, a i te tau 1959 i whakarewahia e ia he piiraa mo nga moni a te iwi ki te hanga i te whare wananga o Anzac Memorial Chapel, ka whakatuwherahia i te tau 1966. Ko tōna whāinga matua, heoi, he mātauranga: e āwangawanga ana ki te tūpono o ngā kaitono ki te hinga i muri i o rātau hoa i roto i te ahumahi me te ratonga tūmatanui, i mahi ia i te kaha ki te hanga i te whare wānanga hei whare wānanga tohu; i whakatutukihia tenei i te tau 1967. Mai i te Pipiri 1960 tae noa ki te 1962, ko Wilton te Tumuaki o te Tari Mahere Hauora i te SEATO Headquarters, Bangkok. I whakapono ia he mea nui a Thailand, e kii ana "ki te hiahia koe ki te pupuri i te Tonga ki te Tonga o Ahia, me pupuri koe i a Thailand". Na tana tūnga i āhei ai ia ki te mātaki tata i te kino haere o te āhuatanga i Laos
, e whakawehi ana ki te horapa atu ki Thailand, me te arotahi nui o nga Mana o te Hauauru ki Vietnam ki te Tonga. I tohua ia hei hoa o te Order of the Bath (CB) i nga Whakataunga o te Ra whanau o te Kuini i te tau 1962, ina koa mo tana "whakaaro nui ki te mahi me tana kaupapa kotahi" hei Kaiwhakahaere o Duntroon. I te 21 o Hanuere 1963, i whakatairangahia a Wilton hei rangatira rangatira, a ka riro ia hei Tumuaki mo te Kaimahi Nui (CGS), ka whai i a Lieutenant General Sir Reginald Pollard. I tohua ia hei Knight Commander o te Order of the British Empire (KBE) i te 1964 Tau Hou Honore.
