Same 6.5mm MG mounted in the hull of a Kyugo tank. Yes, for anti-infantry use. But he can carry larger anti-tank weapons, or others, in his hands. Sword, flame thrower, anti-aircraft guns, whatever is needed.
Just think about your usual mech-centric franchise; front mission, patlabor, gundam; you see all sorts of hand-held weapon options. The projectile weapons mostly use shell sizes standard to the era, but in terms of close-combat melee weapons, it's wide open for possibility and improvisation; knuckledusters, axes, combat blades, claws, etc...
Looky here: [link] You may see a club rendered from a busted 88mm cannon (to be filled w/ concrete, welded w/ metal shards, and wrapped in barbed wire by engineers). My clever collaborator also came up w/ a brilliantly simple weapon; a drive sprocket connected to a chain. Perfect medieval style flail weapon.
The WWII mechs aren't that agile, not compared to their aforementioned modern brethren, but they wouldn't have to be, relying mostly on sheer force. Like wrecking balls. Just think; one solid blow to a tank's tracks, a cannon barrel, or another mech's sensitive spots; muffler, exposed joints, head mounted optics, etc... would be quite effective. Melee weapons are relatively easy to produce and they never run out of ammo, so yeah, they're in the game. Even better, w/ such items as the Katana, they reinforce a sense of national identity, and distinguish the particular model as having a specific cultural origin.
Right on. The hood of a blown up deuce-and-a-half could become an impromptu shield. Or the shurzen (armor skirt) from a Panzer IV. As far as combining goes... we did a lot of hand-held cannons w/ co-axial MGs, as you'd see on a real tank turret. Flammenwerfer + MG, etc... Also have a flak gun + IF searchlight combo.
I always thought it was cool (despite my general feeling on the war) when soldiers in Iraq made that 'Mad-Max' shop to upgrade Hummers -adding extra armor, turrets and so forth. But this sort of improv engineering has been going on in the military forever. That's sort of the idea behind that Bigfooted Jeep I did: hedgecutter from a Sherman, wheels from a Brit Armored Car, extra armor from a halftrack... upgrades don't always come from a factory.
Well said! When the chips are down, and your running out of luck; you can always MacGuyver yourself out of the situation! That aside, fear breeds hard work and originality -in most cases- so you'll usually end up -on the battlefield- creating something both useful, and unknown to enemy troops. Ambush factor +1, to put it simply :U
Definitely a nickname given to it by US GIs... in keeping w/ all the nicknames given to this series of WWII mecha: Big Joe (US), Big Tom (UK), Big Ivan, Big Fritz... you get the idea. Seems very likely such monickers would arise if these things existed. Typical of that generation's sense of humor, I think.
It'll get a proper Japanese name and numerical designation as the design itself gets ironed out!
