The Blood God Army was stationed on the snowy mountain to guard the abyssal passage. The Federation also used the desolate, secluded location to test out a variety of superweapons. Of course, the abyssal creatures were undoubtedly the best test subjects. As a result, all high-level weapons were given to the Blood God Army almost at once for testing and experimentation.
The Blood God Army was given priority when weapons like the heavy-ion beam were being distributed. Although the Central Army Corps had it as well, it was not considered part of the organizational system.
The heavy-ion beam cannons utilized by the Blood God Army were considered the most powerful heavy-ion weapon.
