I-Kangaroo - igama elivamile labathwali bezisebenzi ezihlomile emabuthweni ama-Allies phakathi neMpi Yezwe II Inkampani ethwala izikhali ikhiqizwa kusukela ngo-1942. Isisekelo sokudalwa kwayo kwakuyimathangi aphakathi kochungechunge lwe-M3 ne-M4, lapho i-undercarriage yaboleka cishe ingashintshiwe. Eshidini elingaphambili legumbi lokulawula, ama-flap amabili anezikhala zokubuka ezigoqeka phezulu afakwe, abanjwe ngokuvundlile ngosizo lwama-racks endaweni eqoshiwe. Igumbi lokulwa selishintshiwe laba ithimba lokuhlala, elingahlalisa amasosha ahlome aphelele angu-15. Isibhamu somshini esilwa nendiza esingu-12,7 mm sibekwe ngaphezulu kweqembu elihlala phansi. Indawo yamandla kanye nokudlulisa kuhambelana namathangi ayisisekelo asebenze njengesisekelo sokwakhiwa kwesiphathi sezisebenzi ezihlomile. Injini ye-Continental air-cooled carburetor yasetshenziswa njengendawo yokuphehla amandla, kwasetshenziswa i-gearbox yemishini enamagiya amahlanu. Ku-undercarriage, kwasetshenziswa isibungu se-raber-metal 406 mm ububanzi, esiqinisekisa ukucindezela okuncane okuphakathi komhlaba okulingana no-0,7 kg / cm.2. Inkampani ethwala izikhali ekuqaleni yayihloselwe ukuphelezela ukufakwa kwezikhali ezisindayo ezizishayelayo (ukuthutha ingxenye yabasebenzi nezinhlamvu), kodwa futhi isithole isicelo sokuthuthwa kwamasosha ahamba ngezinyawo. Isici saso sasiyisivikelo sezikhali esinamandla kakhulu kumuntu ophethe izikhali - 38-50 mm. Izici zokusebenza Ukulwa nesisindo I-21,35 T Ubukhulu:   isikhathi 6045 mm ububanzi 2665 mm ukuphakama 3050 mm Abadlali Abantu abangu-18 Impi 1 х 12,7 mm isibhamu somshini Izinhlamvu Imijikelezo engama-1000 Ukubhuka: i-hull forehead 50 mm uhlobo lwenjini carburetor "Continental", uhlobo R975-C1 Amandla aphezulu 400 h.p. Максимальная скорость I-38 km / h Ukugcina amandla 225 km
