"Lightningbolt" 115mm Automatic 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 smoothbore 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 can deliver a rapid burst of anti-armor devastation at the cost of manually replacing the spent magazine with a new one. In addition, 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 systems.

In a rare moment of sheer genius, ingenuity, and economic viability, every single team assigned to create the Lightningbolt Anti-Armor Gun pulled on the same string, working nearly every component into a work of art. The loading mechanisms, mechanical arm, and even loading system have all been refined and prototyped beyond what the initial estimates have projected. Credit where credit is due, those assigned to the project were good, but they have outdone themselves, creating an autoloading system beyond even those currently being developed within the USSR and USA, eliminating the need for magazines in exchange for a minimal increase of weight to armor the belt and loaders. They even managed to incorporate automatic loading of different ammunition types and limited ability to shoot in a 270° arc at pre-determined targets independently. The latter capability is still deep within the prototypical stage. It is best used while standing, against stationary targets, and in conjunction with rangefinders, unless an ambush in a prepared environment is enacted.

"Thunderfire" 57mm Tri-barrel Autocannon (Mech Rifle) - OBSOLETE
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. In addition, 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 have also been adapted into an ammunition feed that is quite resistant to jamming. However, the belt-fed system prevents on-the-fly switching between anti-armor and anti-aircraft ammunition.
(1+3+4=8)
Despite the difficulty in the production and design phases, the Thunderfire Tri-Barrel Autocannon has met all targets and leaves little to desire from its design. However, increases in weight and a lowered maximum of bullet-throughput had to be accepted as material constraints of the bullets could otherwise lead to premature explosions or jammings within heated Thunderfires. Still, this weapon will prove an adequate point of development for future endeavors into Iron Tiger-Deployed AAs.

"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.
(5+6=11)
Despite the latter use of the Dragon's Tooth indicating a titanic breach of security, as well as the outbreak of war on a possible global scale, it is an excellent hold-out weapon as every person within the military, from the generals to the planners, all the way down to the grunts at the bottom of the pole assures you. The reason soldiers are still being issued knifes today is that soldiers will still use them, despite engagement ranges often being more than a hundred meters.

"Dragon Spite" 57mm Mech Autorifle (Automatic Mech Rifle)
The 57mm caliber has been retained due to its ability to punch through dense underbrush and unreinforced walls without losing too much energy immediately after, both locations where the SL is expected to fight. It is a single-barrel electrically driven chain gun held in the mech's hands, firing bursts of one of two new ammunition types developed for the caliber and used against ground targets rather than aircraft.
-HEDP bursts are effective against lightly armored targets and infantry, the contact fused HEAT warhead capable of puncturing the protection of the former. At the same time, the AoE of the fragmentation casing can shred groups of the latter type.
-APDS bursts are effective against more heavily armored targets, even having enough penetration to go through some MBTs' side and rear armor if the SL finds itself close enough in a flanking position. Beyond that, it can also punch through walls and continue into whatever, or whoever is on the other side, bringing a cloud of spall fragments with it.
-Ammo switching mid-combat has been achieved by having both reservoirs of ammo run into the same linkless feed mechanism before reaching the Dragon Spite. To swap from one type to the other, the feed system simply back-feeds the unwanted ammo type into its magazine until the feed is clear, then pulls from the other magazine instead.
(12+12 =24)
Developed:
"Dragon Spite" 57mm Mech Gatling (Mech Gatling)
Thanks to massive advancements in cooling, robotic, and electronic development, the switching of munition types occurs within a mere 3.4 seconds, with the weapon capable of unjamming itself after a cycle of reloading again. Furthermore, typical bursts of firing last for 4 seconds before requiring a 3-second cooldown, though this can be extended to 21 seconds with the barrel needing replacement afterward.
"LIAR" L246 Anti-Infantry Weapon System (Automatic Mech Rifle)
A simple rifle-caliber machine gun, the L246 (nicknamed "LIAR"), is held in a vambrace mount on the outside of the forearms, kept that small a caliber to avoid taking up too much space in such a small location. It provides a lower-collateral way of dealing with hostile infantry and unarmored vehicles than other non-zero-range weapons. Technically two can be mounted, one per arm, but most of the time, only one will be used to reduce the possibility of any interference with equipment held in the hands.
(8+11=19)
Developed:
Despite the low-hanging aspirations of this anti-infantry system, the engineers working on it have outdone themselves in a bid to one-up the Dragon Spite teams, though they fell short while doing so. That is not an insult to them, but a compliment to both, as the LIAR managed to overcome all problems it was anticipated to have.
"Pouncing Cat" ATGM (1-Shot Missile Launcher)
Developed as a low-recoil, lighter-weight anti-tank alternative to the Lightningbolt, the Pouncing Cat is a 1-Shot HEAT missile operating using laser beam riding principles, making it difficult to jam, and is also able to receive information mid-flight from the launcher through modulation of the guiding beam. It is expected to have a much lower ammo pool (6 Missiles) than the Lightningbolt due to the larger size of the missiles than the tank shells, but this is an acceptable tradeoff.
-It takes many of the systems from the Lightningbolt, such as its ability to reload itself and swap between alternate ammo types and the ability of the launcher to aim at a target individually in its firing arc without pilot direction. The latter keeps the missile guided towards the target after launch, even as the pilot has shifted their attention and mech away to engage a different enemy.
-The alternate ammunition type is a missile capable of overfly top attacks using an explosively formed penetrator pointing directly downwards to triggers as the missile is guided over the top of the target. It comes in two subvariants depending on the target, one that produces a single large penetrator and one that creates a spread of smaller penetrators. Further, the missiles can listen to the modulated laser to be manually detonated by the pilot at any point in flight and roll to a limited degree mid-flight. These two combined allow the Pouncing Cat to launch its EFP in any direction on a plane perpendicular to the flight path, letting it "shoot" around corners the SL may not be able to aim around itself.

While the ability to shoot around the corner has not been able to be implemented, its ability to be moved around the same by a skilled operator with a limited degree of accuracy has been retained.
"Heavenly Response" Superheavy Mortar
Taking advantage of the Water Buffalo to move something by mech that has given up all pretense of being fired while mounted, the Heavenly Response is a 250mm mortar and an attached crate of ammunition carried into position by the Water Buffalo. Once there, a single mech can set it up on the ground and operate it, though teams of two are usually sent so one can provide a lookout and protection for the one serving the mortar. As it is an entirely separate weapons system not connected to the SL, the Heavenly Response does not interface with the Tigerlink system. So the pilot must rely on infantry or other mech spotters to adjust aim. The enormous payload capacity combined with our ridiculously durable electronics has some engineers salivating over the possibility of guided mortar shells that still pack a massive punch.
(1+9=10)
Developed:
As advertised, one extremely large mortar. Though, at this point wouldn't it be more accurate to simply call it artillery?
