D-6

A mech was usually meant for combats - treading the war field, firing missiles and lasers to annihilate the enemies - unless it was a non-combat model, a more commercialized unit, like an engineering model for example, instead of weaponry it was "armed" with ore detecting mechanism as well as the other devices; the maintenance model was equipped with professional maintenance tools and was meant to repair all sorts of damage on a mech or a spaceship. There was also the rescue units which, as the name suggested, was created for rescuing wandering pilots sending SOS signals.
