Ishikawajima-Harima followed an unusual path for a defense contractor. Originally a research and development company specializing in industrial equipment, Theodore Kurita himself helped guide the company from consultant to manufacturer with I-H’s introduction of the Void battle armor.

I-H’s ramp up for the Void was nearly unprecedented. Twin plants on Agematsu and Loysville were able to get the suit into the hands of the DCMS in time for the Black Dragon uprising in 3067. During the tension that gripped the Combine following that event however, I-H realized that it had a problem.

While the production lines on Agematsu could be protected by normal security forces, the lines on Loysville had unique environmental concerns that made a normal garrison difficult at best.

Loysville’s manufacturing plant lay on a stretch of arctic coastline near Bitter Lake, the capitol city. This site was chosen for its proximity to the primary planetary spaceport, as well as to a ready source of geothermal energy for power. Unfortunately the bitter cold meant that many vehicles and nearly any sort of conventional infantry could not operate for extended periods of time.

While the DCMS did have several infantry units that I-H was able to consult regarding arctic operations, I-H came to the conclusion that outfitting a conventional security force to operate indefinitely in sub-zero conditions was likely to cause an unacceptable level of personnel turnover. They attempted to adjust their security strategy to limit the use of infantry as much as possible, but eventually came to the conclusion that some sort of boot-on-the-ground security would always be necessary.

Accordingly in 3070 they used their expertise in making the Void battle armor to help solve the issue. I-H scientist and engineers began work on a low cost, environmentally sealed exoskeleton for the use of their own internal security forces. In January of 3070 the schematics were finalized. By March the first field testing prototypes had been produced. On November 2nd the first of a limited run of production units stepped off the assembly line.


The new suit would be known as the Tsuchi. Like the Void, I-H’s first foray into battle armor production, the Tsuchi is named for one of the elements of classical Japanese philosophy. Tsuchi is the element of earth. Earth is the element associated with stability, and I-H felt the name was a good portent for a design intended for use with security forces.

The Tsuchi shares an additional philosophical link with the Void. When the Void was first introduced, observers noted that it was very tall. This ultimately was shown to be the result of I-H’s efforts to allow the Void to fit nearly any body type, up to and including the massive Elemental Clan genotype. Likewise the Tsuchi is able to accommodate a wide range of potential wearers.

Rather than simply allowing for a huge amount of internal space however, the Tsuchi uses an unusual modular construction system that allows individual components to be able to be re-sized for each user. A skilled armorer can fit a Tsuchi suit to a new user in around an hour. This is referred to by I-H security personnel as “tailoring”.

The quick and efficient use of the system means that the Tsuchi is able to be well armored for a PA/L system. It allows for decent mobility as well. The tailoring process allows for movement to be much more fluid than a typical power armor system. Even the armored gloves on the Tsuchi are renowned for allowing for much better fine object manipulation than is standard.

To aid in the mobility I-H did elect to equip the suit with a set of jump jets. Under normal circumstances these jets are locked out by the squad leader to prevent unfortunate incidents. If an emergency is declared, they allow a squad of Tsuchi-equipped troopers to respond much more quickly than traditional foot infantry.

Like most PA/L systems, the Tsuchi has no built in weaponry. Tsuchi troopers carry normal infantry weapons in the same way normal infantry would. It does however have a bit of specialist equipment for use in the harsh conditions of the Bitter Lake plateau.

The most obvious is the environmental system. I-H equipped the Tsuchi with full environmental sealing with an air exchange system. This means that a trooper in one of these suits can breathe normally even during one of the plateau’s infamous wind storms. It has an active heat management system that will keep the trooper at an optimum temperature so long as the suit has power. It even allows a security unit to operate near volcanic Sulphur banks without exposing the wearer to poisonous gases.

The other specialist system is the heat sensing system. In the bitter cold of the region it allows the wearer to be able to spot potential threats at a distance even in blizzard conditions. I-H developed the system to be highly sensitive to temperature variations, allowing it to discriminate between a normal human, a running engine, or even a volcanic eruption. It has been used extensively by I-H not only for the purpose of spotting intruders, but also in a search and rescue capacity.


While the Tsuchi was originally developed for internal use, interest in the suit from other sources has meant that it was eventually offered for sale. The Loysville plant is not the only location where environmental hazards make deployment of conventional infantry untenable. Industrial security departments from Kessel to Small World tested the Tsuchi for use in their own unique circumstances. While the Tsuchi would never supplant the Void as I-H’s primary production focus, it would be a decent profit center for the company.

Several military organizations tested the Tsuchi as well. Mercenaries, planetary militias, and even a few DCMS units ordered test suits to see if the Tsuchi would fit within their forces. While many liked the suit, its lack of stealth armor limited its utility as a scout, and the ultralight design meant that it was not tough enough to occupy the role of a traditional battle armor suit.

In addition, during a few of these deployments a design flaw was discovered in the modular “tailoring” system. While it was quite good for allowing a suit to be re-used by another trooper, the modular design was prone to excessive wear while in the field. In a garrison role, with easy access to repair facilities this was not an issue. On campaign it meant that a typical Tsuchi suit only had an operational time between refit of only a few hundred hours.
