I've been trying to design functioning mecha for the past couple of weeks, probably for the Human faction of our god universe.

As can be seen, this is mildly difficult. Balancing protection vs functionality vs profile is a lot more work than it first seems, especially in a mech. In a tank, there is so much real life reference work that you can just copy and paste depending on what kind of design you would like. With Mechs, there's pretty much no design that seems to really take things like ammo stowage, propulsion layout and crew protection into account.

This basic design is for a two crew Cazador, pilot and gunner. The propulsion units are mounted inside the legs, driven by a generator mounted in the lower hull front. The middle of the lower hull is taken up by the mountings for the legs and in the center, the rocking cradle of the turret. This tilts sidewards to compensate for the tilt of the hull and rotates the turret through 360 degrees. The turret itself is oscillating, meaning the gun is mounted fixed inside and the whole turret elevates to lay the gun. This also simplifies the autoloader design.

The ammo is stored in two pieces, with the propellant in a loading track inside the turret, and the shells inside an armored carousel in the rocking cradle, housed in disposable casettes. The gun itself has attached to it a six shot cylinder, which is charged with propellant, while the shells get elevated from the carousel into the turret three a piece, and stowed in a lifter directly below the gun. Upon firing, the recoiling gun spins the cylinder, throws out the spent casing to the right into the ejection chute and as it goes forward automatically lifts one shell from the magazine to the breech. Then the rammer behind the propellant cylinder rams the charge and shell together, and as it withdraws resets the firing mechanism.

This allows for rapid firing of three round bursts, with about one shot a second and a pause of 8 seconds inbetween to charge another three rounds from the carousel in the hull into the turret.

The crew is housed (not drawn here) in the back of the hull, with a seperate firewall seperating them from all volatiles inside the hull and the turret. Because the legs have their drives inside them, the machine can return to base on emergency power even with the hull burnt out and the turret missing.

Armor is 90 mm of composite, quick detach armour on top of 25 - 45 mm of compound backed with armoured steel. Spall liner is present inside the crew space only to save weight.

This vehicle also has an active protection system and 360° coffin display systems for the cockpits and body-actuated controls (Such as head controlled rotation of turret and gunlaying, and neurally linked movement systems.).

Total ammunition load is probably around 30 rounds.
