Umthetho wase-Federal (I-United States Code, Isihloko se-10, Isigaba 2683) sidinga abaphathi bezempi ukufaka isikhathi esifanayo sokuphuza njengoba isimo sezempi sisezingeni.
Okuwukuphela kwalomthetho lo mthetho uma ngabe isisekelo sitholakala engakini ngamakhilomitha angu-50 eCanada noma eMexico, noma izwe elineminyaka ephansi yokuphuza, umphathi wokufaka isicelo angase athole iminyaka ephansi yokuphuza izisebenzi zempi ngesisekelo. Lo mthetho uphinde uhlanganiswe ku-DoD Instruction 1015.10, ethi:
Isikhathi sokuphuza okungenani ekufakweni kweDoD esivela kuHulumeni (kufaka phakathi iSifunda saseColumbia) kuzohambisana nesikhathi esasungulwa ngumthetho walowo Mbuso njengoMbuso wesilinganiso esiphansi sokuphuza. Isikhathi esincane sokuphuza sisho iminyaka encane eyenziwe ngabantu abangathenga, abanayo noma abaphuze utshwala.
Uma kwenzeka ukufakwa kwe-DoD kuMbuso ongaphezu kowodwa noma kuHulumeni owodwa kodwa kungakapheli amamayela angu-50 wesinye isizwe noma iMexico noma eCanada, ukulinganisa okungenani okungenani kulelo doD ukufakwa kuyoba yindawo ephansi kunazo zonke yoMbuso lapho iDoD ukufakwa kutholakala noma uHulumeni noma igunya laseMexico noma eCanada elingamakhilomitha angu-50 ku-DoD yokufakwa okunjalo.
Isikhathi esincane sokuphuza ekufakweni kweDoD esingaphandle kwe-United States kuyoba neminyaka engu-18 ubudala. Ubudala obuphansi bokuphuza buzobe busekelwe ezivumelwaneni nezivumelwano zomhlaba wonke nasesimweni sendawo njengoba kunqunywe umlawuli wendawo yokufaka indawo. Umlawuli we-DoD ukufakwa angase akhiphe izidingo ezingenhla uma lowo mlawuli enquma ukuthi ukukhululwa kulungile ngenxa yezimo ezikhethekile.
Izimo ezikhethekile yilezi zikhathi zempi ezingavamile, lapho kungenjalo, njengeqembu, lifaka ukufakwa kwezempi njengesenzakalo sezempi esiyingqayizivele njengesiphetho somsebenzi wezempi okhuthele noma umkhosi wokuqokwa kwenkonzo yempi noma inhlangano. Umcimbi kumele uqhutshelwe ekufakweni kwezempi. Umlawuli uzoqinisekisa ukuthi izilawuli ezifanele zikhona ukuze zivimbele ukulimaza amalungu eNkonzo yamaMpi noma umphakathi ozungezile.
Ngenkathi umthetho nomyalelo we-DOD kuvumela ukuphuza phezu kwalabo abangaphansi kweminyaka engama-21 uma isisekelo sitholakala engakapheli amamayela angama-50 ezwe evumela ukuthi iminyaka ephansi yokuphuza, uNobhala weNavy akhiphe umgomo weNavy (owawuhlanganisa iMarine Corps), okwenqabela umkhuba. Kuze kube yileso sikhathi, ukuqhutshwa kwezikebhe nabaseMarines ezindaweni ezisemaphandleni angamakhilomitha angu-50 eMexico ( njengeCamp Pendleton ) kwakuvamile.
Eminyakeni embalwa kamuva, i-Army yahamba ngokulandela, ivimbela uku-ukuphuza ukuphuza ezisekelweni zayo (njenge- Fort Bliss , eTexas, ne- White Sands Missile Range ) eyayingamakhilomitha angaba ngu-50 eMexico. I-Air Force ayizange ivumele abaphathi be-installation ukuba bathole "umthetho we-miles-50." Ngo-1997, uMlawuli WaseMarine wakhipha inqubomgomo eyayivinjelwa nokuphuza ukuphuza iMarines egijimise phesheya kwamanye amazwe kuze kube yiminyaka engu-21, noma ngabe izwe lasekhaya liba nomthetho ophansi wokuphuza.
Kodwa ngoSeptemba 2006, i-Corps yanciphisa isikhathi sokuphuza iMarines eJapane ibe ngu-20 ukukhombisa iminyaka yokuphuza yendawo.
Ngokuqondene nomthetho "wezimo ezikhethekile," kufanele ngikhombise ukuthi zonke izinsizakalo zidinga umlawuli wokufaka ukuthola imvume ekhethekile evela endlunkulu yabo yesevisi ukuze kunciphise iminyaka yokuphuza kulezi zenzakalo ezikhethekile.
Isibonelo, uma i-Air Force Installation Commander ifuna ukunciphisa imfuneko yobudala bokuphuza iphathi ukugubha "Usuku lokuzalwa" lwe-Air Force, uzodinga imvume evela ehhovisi le-Air Force Chief of Staff. Ngoba umlawuli wayezoba "ngokunamathela entanyeni yabo," (uma kwenzeka kwenzeka okuthile), ekuhlangenwe nakho kwami, imvume enjalo cishe ayicelwe.
Nokho, i-Marines ingaba nefilosofi ehlukile.
Ngo-Ephreli 2007, uMnumzane waseMarine Corps wasayinwa ngomhla ka-MARADMIN 266/07, wavumela uMarines oneminyaka engu-18 ukuba aphuze emachwebeni angaphandle uma umthetho wezwe lomhlali uwuvumela.
Umlayezo uphinde unikeze "ukukhanya okuluhlaza" kubaphathi beMarine Corps ukuba babe namaqembu esisekelo lapho uMarines oneminyaka engu-18 angase aphuze khona, ngezikhathi ezikhethekile ezikhethekile, njengokubuya kweyunithi ekuthunjweni kokulwa, noma ngesikhathi sokuzalwa kwe-Marine Corps 'Birthday Ball . Lo myalelo uqinisekisa ukuthi abaphathi "baqinisekise ukuthi izilawuli ezifanele zikhona ukuvimbela ukuphazamiseka kwamalungu omsebenzi wezempi noma umphakathi ozungezile," ngesikhathi sezo zenzakalo.
