'Allelusia' clockwork armor

Allelusia class clockwork powered armor is the standard issue armor of the ‘Army of the Dragon king’. Because of its self-reproduction unit, ‘Clockwork hearts’, the department of munitions doesn’t suffer about component supply problems anymore. If there was no such innovative technology like Clockwork hearts, Allelusia can’t be selected as realm of dragon’s standard armor.
Anyway, Allelusia is the most advanced personal armor in the world. By the high tension clockwork motor and strength amply, wearer can ignore weight of thick plate mail.
