i a under th e impression from one of the good youtube videos on spear tactics used in the ancient world that someone posted in another thread.
You would balance the shield with your leg, basically your greaves and your leg will help keep it from going down. I am not a real expert on this stuff, but I know for sure, theres something calleda boss in shields which balances out the scrutum.
I can really explain it, but look at pictures of a Scrutum or any other shield. There will be a big round thing near the center, basically you hold that on the other side and the shield will be balanced.
