ARA modifications: the original rig and its single monolithic animation
are not used. The geometry was adapted to the simulator's scale and
coordinate system, re-rigged to the canonical 59-joint skeleton, and
extended with finger skin weights, vertex colors, a team-colored
team-colored eye, nape and shoulder lights, attachment points, and 44 ARA animations.
ARA modifications: the original Ogg file was selected, converted to
mono, normalized, and encoded as Opus for the bullet fly-by effect.
This adapted sound remains available under the same license.
