In AmE, reinforced /ˌriːɪnˈfɔːrst/ rhymes with forced /fɔːrst/, enforced /ɪnˈfɔːrst/, and unreinforced /ˌʌnˌriːɪnˈfɔːrst/, all ending in /fɔːrst/. The related words force /fɔːrs/, enforce /ɪnˈfɔːrs/, and reinforce /ˌriːɪnˈfɔːrs/ are spelled with -orce but pronounced without the final /t/; they do not rhyme with reinforced. In BrE, the /r/ is silent, so the same endings become /fɔːst/.
