The head, which is a high latency and easily confounded decisionmaking apparatus, could be more efficiently replaced with a rotary cannon. Genitals are not required on the battlefield, they could be substituted instead by some form of tractor unit, integrated missiles or TEL Transporter Erector Launcher.
Alternatively, a good genital replacement munition might be an Artillery Fired Atomic Munition (AFAP) such as the 280mm M65 Cannon / W9 nuclear warhead during Operation Upshot-Knothole Grable.
Limbs are best replaced with landmines, some form of system dispensing area denial. They also function to remove more limbs, thereby increasing efficiency.
