Overview

Beachhead is a squad-level Pacific theater wargame published by Yaquinto in 1980. Set during 1942-1944, the game simulates American amphibious landings against Japanese island defenses. Each hex represents 25 yards, each counter represents one squad (~10 men), one heavy weapons team (~5 men), or one tank, bunker, emplacement, or gun. Each turn represents 20 minutes. The game is divided into basic and optional rules, with two main scenarios: “Opposed Landing” and “Banzai!”

Components

Setup

Players select a scenario. “Opposed Landing” has Americans attempting to land and force their way off the beachhead against prepared Japanese defenses. “Banzai!” has Japanese defenders launching a counterattack to retake a jungle plantation. Units are placed according to the scenario’s deployment charts. Japanese defensive positions (bunkers, gun emplacements) are placed on the map.

Turn Structure

Each Game-Turn represents 20 minutes:

  1. First Player Movement Phase: Move units within movement allowances.
  2. First Player Direct Fire Phase: Resolve direct fire attacks.
  3. First Player Indirect Fire Phase: Resolve artillery and mortar fire.
  4. Second Player Turn: Same sequence of phases.
  5. End Phase: Advance turn marker, check victory conditions.

Actions

Scoring / Victory Conditions

Scenario-dependent. In “Opposed Landing,” the Americans win by establishing a beachhead and moving units off designated map edges. In “Banzai!”, the Japanese win by recapturing the plantation area. Victory may also be determined by casualty ratios.
