4th‑Century BCE Land Scenario Generator — nominal 6′ × 4′ Board • 24 Squares

Grid: 24 squares (1′ each). Numbering: 1–6 Attacker DZ, 19–24 Defender DZ; centreline between rows 7–12 and 13–18. In Fair & Open, formations may not deploy beyond the centre of their DZ squares unless wholly in Woods/BUA. Length = hours to Dusk (or to Dawn for Night). Tags (FP/FL/CP/CM/CL/CH/S/T/ART) map cleanly to Basic Impetus list styles. Pike = FP; hypaspists/guards = elite FP.

Deterministic: no randomness. 4th‑c mixes reflect Macedonian pike/cavalry ascendancy, Theban depth and cavalry use, late Achaemenid cavalry/archery with some scythed chariots, and Sicilian/Carthaginian combined‑ops. Built‑in Siege Equipment picker appears when Situation = SIEGE. Manpower outputs in hundreds/thousands; you unitize for your rules.

Notes (4th‑c): Macedonian pike + heavy cavalry reshape open battles; Theban depth and better cavalry appear; late Achaemenid use archery/cavalry with some scythed chariots. Sicilian/Carthaginian theatres feature coastal/port actions. Built‑in siege picks model torsion artillery, towers, moles, mines, and port booms/assault bridges.
Tags (FP/FL/CP/CM/CL/CH/S/T/ART) + Siege tags map cleanly to Basic Impetus. Treat artillery as primarily suppressive against parapets/crews; breaches come from RAM/MINE/escalade.
