Question about the Roman \'wedge formation\'

[jkaler48]

Well, what we know is that the Romans used a formation called cuneus, wedge, and that ad cuneum, to the wedge, was one of the commands that sent them there.

What we don't know is what that formation looked like, or how it was organized. Heck, we aren't even completely sure how a command to change formations was issued to 20K clattering, jingling, foot-tramping troops so they knew what to do. Voice, relayed voice, horn signals, signum (standard) signals, or some combination...all are good suggestions, but little is known about the specifics.

One can speculate that a hand and arm signal could be given by the Centurion. Centurion steps forward V paces raises arms in a "V" and commands "Ad Cuneum" Standard Bearer
gives the signal for "Attention" Cornicen sounds the "Ad Cuneum" (There are limits to how many unique standard signals that can be easily recognized)
