It has been about 5 or 6 years since I have been involved with the ATA, but from my experience, they mainly teach weapons forms. Not much that I saw in the way of weapon usage and defense. If I am wrong, let me know. When I left the ATA, they were also beginnig to incorportate weapons requirements into the black belt ranks. 1st dan was the chucks, 2 was the stick I think, 3rd was the staff, and so on. If I am misinformed, let me know.
