Weapons Package: Ranged Assault
[] "Lightningbolt" 115mm Smoothbore Anti-Armor Gun (Back-mounted)
Inspired by the Soviet U-5TS tank gun mounted on the T-62, the world's first tank-designed smoothebore cannon has been adapted to fit on a deployable arm behind a bipedal chassis. While capable of firing conventional USSR-made shells, the gun's alloy and loading system are modified from the anti-tank variants among the laufpanzer prototypes. Featuring a 10-round magazine and autoloader mechanism, the Thunderbolt system is capable of delivering a rapid burst of anti-armor devastation at the cost of having to manually replace the spent magazine with a new one. A "Two-Mech" system is advised when deploying the chassis it's mounted on, with one unit to fire, the other two load, or both units taking turns firing and reloading their own systems.
Weight: 2.35 tons (original weight) >>> 3.2 tons (new alloy, weapon addons)
[] "Thunderfire" 57mm Tri-barrel Autocannon (mech rifle)
Soviet-made, the 57mm AZP S-60 short-to-mid range single-barrel autocannon has been adapted into a tri-barrel configuration capable of shredding not only aircraft but even some armored vehicles, albeit from more vulnerable angles. One of the laufpanzer alloys described amongst the original notes has allowed for a tri-barrel rapid-fire mech-sized autocannon rifle that can fire in respectable bursts without risk of overheating while also offering considerable protection from collision and kinetic damage. The robust internal mechanisms in the original laufpanzers has also been adapted into an ammunition feed that is quite resistant to jamming. The belt-fed system, however, prevents on-the-fly switching between anti-armor and anti-aircraft ammunition.
Weight: 5.14 tons (original) >>> 3 + 1 tons (4 tons, rifle + 300 rounds ammo)
[] "Dragon's Tooth" Bayonet/Combat Knife
Made with the most durable alloy present in the current designs, the Dragon's Tooth is designed primarily for survivability. It is meant to last through multiple uses before even beginning to show signs of stress. A last ditch weapon, it can be used to destroy enemy armor from close range, or to take down hostile mechs in close combat, in a worst-case scenario.
Weight: 0.8 tons (very dense, but also very durable)
Note: I'd also like to point out that the weapons I adapted the ranged weapons from have also been exported to China and have their own Type-Number designation. It shouldn't look strange if we buy them from our neighbor.
