THEM Anime Reviews has noted that the Arm Slaves, like most real life vehicles, are done so meticulously that fans of mecha series would "scour online catalogues for tech books and sketches." Bureau 42 says that the "mechaSlave action in the show is very well done. While I can't compare the action with other more grounded mecha shows like Patlabor, the combat is very well done and easy to follow, and visually interesting." Triforce commented that Arm Slave battles in the Full Metal Panic! series would be able to keep viewer's attention to the show.
