Where did tanks fit in the organizational comparison?

Were tanks already included under artillery rather than a separate branch in that comparison?

The viewer's correction is accepted: tanks are placed within artillery as a subsection, despite having been mentioned separately.

A viewer challenges the earlier listing of tanks as a separate arm by placing them under artillery until the mid-1930s. The reply accepts that correction and describes tanks as a subsection within the larger arm. The earlier separate mention was intended to make tanks visible in the comparison. The exchange criticizes the confusing categories produced by political compromise in army organization.
