1:72 "Ackwisch" walking tank (inspired by Patlabor & Gundam) & HMMWV on display base
A fantasy mecha project, inspired by Patlabor & Gundam. The plan was to build a ‘realistic’ hexapod tank, even though with an SF touch.
The vehicle is not 100% supposed to match anime style – but the concept is pretty popular in Japanese animation, SF or special interest genres like Ma.K., so I think calling the “Ackwisch” (Hebrew for “Spider”) mecha is fine.
While the mobility of walking vehicles is arguably higher than that of wheeled or tracked vehicles, their inherent complexity has limited their use mainly to experimental vehicles. Examples of real manned walking vehicles include General Electric's Walking truck, the University of Duisburg-Essen's ALDURO and Timberjack, a subsidiary of John Deere, built a practical hexapod Walking Forest Machine (a harvester for rough/delicate terrain).
One can argue about the sense of a legged tank, though. It's slow, it has a high CG an silhouette, it's mechanically complex, it needs a lot of space in order to manoeuver, and you cannot deny the laws of physics: ground pressure is a SERIOUS issue, for any armored vehicle. A simple wet lawn can stop a tracked medium battle tank with a relatively large footprint – how’s a walking tank with only a fraction of area to distribute weight supposed to fare? A modern battle tank like the Merkava easily weights 60 tons and more. You might add for a legged specimen at least 10 more for the legs and their mechanics… so, is a walking tank “realistic”? Certainly not, but it’s cool…. And, since this is SF, it should at least look cool and somewhat menacing... ;)
This project had been waiting on the bench for a while and even saw a major creative interruption, and even then the whole building process took several weeks. Main ingredients are an 1:72 ESCI Merkava II tank kit, PVC doll joints from Kotobukiya for the legs (so they remain moveable, within limits),six resin legs from two ‘Junk Rock Tank’ recast kits in 1:35 scale (from a total of eight – you never know!), and two aftermarket gun barrels made from metal, since the tank received a double gun as a special feature. The commander’s cupola was donated from a 1:87 scale Roco Minitanks M60, otherwise a lot of details had been scratched or improvised – please check the WiP album for reference and single steps.
Construction was pretty straightforward, though, as well as painting, since I kept the tank in a uniform drab color (very similar if not identical to real life IDF tanks, RAL 7008 “Khakigrau”). Weathering was done with a thorough black ink wash and dry painting with various shades of brown, beige and grey, plus some of the artist pigments that were used on the base, too (see below).
The base was created with Styrofoam and plaster on an MDF board, the rock is actually aquarium decoration from a pet store, made from resin. The crater was sculpted into the basic surface.
The surface was decorated with fine sand, water-based paint and artist pigments, the vegetation consists of fine model railroad turf and grass fiber, brush fibers for large weed bushels, some dried real vegetation and a bit of dry moss.
As some space was left on the left side of the base, I eventually added a small vehicle there – my choice fell on a die-cast HMMWV from Dragon. Very fine car model, even though its place and position could have looked a bit more natural if I had integrated earlier into the planning process. But with both vehicles in place, the whole arrangement gains a bit of a meaning, as an observation scene. I still would not call it a diorama, though – it’s just a presentation base that might also be used in future model photographs.
Shooting the tank on its base was tricky, because of the relatively small dimensions of the base – on some of the pics I had to add virtual foreground in order to fill blank space, but otherwise only little “photoshopping” had to be done.
