Okay currently the Hastati and Principes have a Spear/Scutum shield. The Triarii are equipped as Hoplites.
When do the hastati/principes lose the spear? Historically it looks as if they ditch spear for Italian sword, and then go to gladis shortly before 2nd punic war. We don't have room to simulate that. So we need to choose a date where they go from Spear to Sword. Unless you want 3 types of each unit!
Okay so Leves, Accensi, and Rorarii stay in until 211 BC. We can discuss a scenario for a script..
