In June 1944, American Marines and soldiers began the conquest of the Japanese-held Mariana Islands. After a bloody struggle for the island of Saipan, the Americans invaded Guam and Tinian in late July. Guam feel after 20 days of battle; Tinian, after eight. B-29 Superfortress bombers soon arrived on the islands to begin the strategic bombardment of Japan.

Panzer Grenadier: Marianas 1944 is an expansion book for Saipan 1944, studying the battles for Guam and Tinian in 30 new scenarios. Ten of them take place on Tinian, and 20 on Guam - one from the 1941 Japanese invasion, and the other 19 from the 1944 American assault. Everything you need is included with this book and the boxed game Saipan 1944 - no other games or supplements are needed to play any of the 30 scenarios.

Marianas 1944 includes two new maps and 24 new laser-cut, scorchless and sootless playing pieces featuring additional unit types: Japanese truck-mounted anti-tank guns and heavy coastal artillery, Marine flame-throwing Sherman tanks and the entire Guamanian order of battle for World War II.

Display Relevant AFV Rules

AFV Rules Pertaining to this Game's Order of Battle
  • Vulnerable to results on the Assault Combat Chart (7.25, 7.63, ACC), and may be attacked by Anti-Tank fire (11.2, DFT). Anti-Tank fire only affects the individual unit fired upon (7.62, 11.0).
  • AFV's are activated by tank leaders (3.2, 3.3, 5.42, 6.8). They may also be activated as part of an initial activating stack, but if activated in this way would need a tank leader in order to carry out combat movement.
  • AFV's do not block Direct Fire (10.1).
  • Full-strength AFV's with "armor efficiency" may make two anti-tank (AT) fire attacks per turn (either in their action segment or during opportunity fire) if they have AT fire values of 0 or more (11.2).
  • Each unit with an AT fire value of 2 or more may fire at targets at a distance of between 100% and 150% of its printed AT range. It does so at half its AT fire value. (11.3)
  • Efficient and non-efficient AFV's may conduct two opportunity fires per turn if using direct fire (7.44, 7.64). Units with both Direct and AT Fire values may use either type of fire in the same turn as their opportunity fire, but not both (7.22, 13.0). Units which can take opportunity fire twice per turn do not have to target the same unit both times (13.0).
  • Demoralized AFV's are not required to flee from units that do not have AT fire values (14.3).
  • Place a Wreck marker when an AFV is eliminated in a bridge or town hex (16.3).
  • AFV's do not benefit from Entrenchments (16.42).
  • AFV's may Dig In (16.2).
  • Open-top AFV's: Immune to M, M1 and M2 results on Direct and Bombardment Fire Tables, but DO take step losses from X and #X results (7.25, 7.41, 7.61, BT, DFT). If a "2X" or "3X" result is rolled, at least one of the step losses must be taken by an open-top AFV if present.
  • Closed-top AFV's: Immune to M, M1 and M2 results on Direct and Bombardment Fire Tables. Do not take step losses from Direct or Bombardment Fire. If X or #X result on Fire Table, make M morale check instead (7.25, 7.41, 7.61, BT, DFT).
  • Closed-top AFV's: Provide the +1 modifier on the Assault Table when combined with infantry. (Modifier only applies to Germans in all scenarios; Soviet Guards in scenarios taking place after 1942; Polish, US and Commonwealth in scenarios taking place after 1943.) (ACC)
  • Tank: all are closed-top and provide the +1 Assault bonus, when applicable
  • Tank Destroyer: do not provide the +1 Assault bonus, even if closed-top (SB)
  • Anti-Tank Gun Carrier: half-track with anti-tank gun, NOT a Tank Destroyer
  • APC – Armored Personnel Carrier: These are Combat Units, but stack like Transports. They can transport personnel units or towed units. They are not counted as combat units for the +1 stacking modifier on the Direct Fire and Bombardment Tables (4.4). They may be activated by regular leaders and tank leaders (1.2, 3.34, 4.3, 5.43). They do not provide the +1 Assault bonus (ACC).
  • River Vessels: see Rule 15.2 ~ 15.22
  • Unarmored Weapon Carriers: These are unarmored halftracks (Bufla and Sk7/2) or fully-tracked vehicles (Karl siege mortar) with mounted weapons. All are mechanized, except the BM-13 (Katyusha rocket launcher mounted on a truck). They are weapon units, not AFV's, so they are never efficient and cannot be activated by tank leaders. (SB)

5 Errata Items
Errata item for JayTownsend

Scenarios #19 – 20, 22 - 30:

The US initiative and Morale ratings are switched. Sorry I got dyslectic.

Scenarios 12 & 13 for the Marianas that uses more Marines ENG/PIO counters then you have in the mix, so you/players will have to substitute one Army ENG counters to make up the difference in those two scenarios.

Scenarios 1-3, the visibility is one hex as it was moonless night.

(JayTownsend on 2015 Jan 01)
Scen 1

Marianas 1944 01. White Beach 1 & 2 is also an amphibious landing scenario.

(JayTownsend on 2014 Aug 26)
Scen 22

This scenario calls for 2 Army M-5 tank platoons. Unless I misplaced one, my Saipan game only has 1 Army and 1 Marine M-5 unit, so I recommend using the Marine as the second one.

(thomaso827 on 2014 Aug 11)
Scen 30

Scenario #30

It should be one Japanese 81mm counter in the setup not a 120mm counter.

(JayTownsend on 2015 Jan 01)
Overall balance chart for 1466

The 8-3 Marine Infantry counter appears in most of the Saipan 1944 and Marianas 1944 scenarios, replacing the 10-3 DF valued Marine counters for those scenarios and is currently published in the most recent Saipan printing.
