Open Battles Solo Mode: GI Joe versus the Romans

This post is about testing the solo rules in Open Battles with aircraft, using the 2-player version of the scenario I designed for the first anniversary of the Airfix Battles Appreciation Facebook group: GI Joe versus the Romans. Open Battles is our working title for the new game under development by Nick Fallon and I (for Modiphius) as a follow-up to Airfix Battles.

The historical background in brief is that on 15 July 1944 the hard-fought, intense battle for St Lo had not yet been won by the Americans of General Bradley’s 1st Army. XIXth Corps had attempted to outflank Hill 122 to the north-east of St Lo for several days, but stubborn German defence had blunted his lead divisions. Therefore, he called upon the recently-arrived 35th Division to carry out a more direct attack. Approaches to Hill 122 were covered by the villages of Emilie and Les Romains. The scenario represents part of the attack of the Nebraskan National Guard 134th Regiment on the hard-core survivors of the German 352nd Division, the same division that had opposed the Americans at Omaha Beach on D-Day.

I opted for the US in this game, as I’d already played (and lost) as the Germans. For the 2-player and solo versions we use only about half of the battlefield, so that we can limit each Force to 19 Stars apiece.

Initial German set-up

German troops. The Captain’s Air Defence Controller attachment is, as you can see, a very new card. He allows the player to buy a Field Fortification in any scenario without needing a Unit tab.

US set-up. The half-track contains my Engineers led by a trusty Lieutenant. I also have off-table Spitfire and Thunderbolt. Also, my Captain has a Forward Air Controller who can call in air strikes anywhere in line of sight.

My US troops. I have a preparatory air bombardment – this represents a few Marauders helping out before we go in.

Preparatory bombing: I chose to bomb the known field fortifications, hoping to pin the 88. But not particularly effective, caused a couple of German losses and pinned the PaK40.

My first card is Rolling Thunder, so I launched an immediate air raid on the PaK40 to clear the way down the left flank. Rolling Thunder permits 2 vehicles to Move then Fire, so it’s perfect for a couple of planes. I can target the PaK in the Field Fortifications only because I have the FAC attached to the Captain in LoS of the enemy square; normally aircraft cannot spot things in cover. The A-OK 88 starts the scenario ready to fire, so it opened up on the Spitfire. Brilliant flying from the pilot meant he avoided all 3 potential hits from the gun, completed his strafing run and caused a casualty on the PaK. The Thunderbolt following up decided to strafe and finished off the crew (terrible cover save rolling from the Germans, because they do get +1 on their cover saves in the trenches there).
However, on the very next turn the 88 fired again at the Spitfire (using its normal Order), scored 3 hits again, and this time the pilot’s luck ran out and he was shot down.

Honours even?

End of Round 1: With the PaK knocked out, both US Infantry Squads have moved up ready to assault down the left flank. German fire has been intense and both have lost men and are pinned.

End of Round 1: First US attack. Note the barbed wire – these “model” pieces are actually extraordinarily sharp! Handle with care because they’re very realistic!

Calamity in Round 2: My assault got under way, and eventually we pinned the dug-in Grenadiers #5 in front of us by using all our firepower including the half-track; the enemy was also down to 3 men. Then disaster! My engineers were hit by an artillery strike and forced to retreat; my plan had been to get them to clear the barbed wire so Squad 11 could get through. Then the 3 German Grenadiers rallied and charged my pinned squad 8, forcing them back as well. It’s not looking good.

First attack beaten off. It was so hairy there that my Captain had to engage directly and beat off the Grenadiers himself.

Situation stabilised a bit. US troops regrouped. Another Thunderbolt strike failed, and the plane was damaged . But we eliminated the German Grenadier Unit #5 as well as the PaK, and caused casualties on their other Grenadier Unit (#4). However, that German Unit in the multi-storey building is tough – extra dug-in, plus it has height advantage, so better range than us and can fire over the hedges without them blocking LoS. We suffered a lot from flanking fire.

Getting ready for another assault.

Round 5: Thunderbolt’s last attack . Coupled with the loss of another squad that retreated off the board in the face of MG fire, it was nearly over for the good guys. I was hit hard by the Engineers’ failure to rally for 3 Rounds – they were supposed to be the mainstay of my attack!

Got to dig deep now! Squad 11 is about to retreat off-table.

Sudden change of fortune in Round 6: Our attacking Engineers, having eventually been persuaded to get back over the hedge, were immediately pinned in the open again, this time by the enemy’s command team consisting of their Captain and an Air Defence Controller (with just a pistol)! Fortunately, this was a very temporary setback. An Artillery Strike on the pinned German Grenadiers holding us up in the centre of the battlefield caused them to rout, so the flank fire was neutralised. At the same time our engineers rallied straight away (!) and shot down the German commander and his side-kick. This meant we just needed half-a-Star to demoralise them, and this was achievable by taking the empty Field Fortification. So, it looks like the US may have pulled victory from the jaws of defeat!

German command team is killed.

Final position: Technically, the game ends when the halftrack enters the field fortification square. I’ve adjusted the duration of the game by changing the victory conditions to – Game ends when all Forces of one side are demoralised; so, in a 2-player game, demoralisation of one side automatically means the other side wins. However, you can always play for the final denouement of taking the Pillbox. In this example, the Engineers have AT(6) + 1 for the Mechanised Assault + 1 for the flank attack. They manage to just about knock it out in this example. It’s quite possible that this will take more than one go, so it’s best to be prepared .

This was a very close game. I’d taken 8 Stars of losses, the Germans 9.5 by the end. For a proper assessment of balance, we’d need to play it a few more times.

The Solo Rules seem to be working fine. Important points to remember when reading the Enemy Behaviour table: aircraft are Vehicles! If the enemy is in a good position, don’t override that by interpreting the Enemy Behaviour table in your favour – for example, an enemy Unit in Cover won’t Move as a result of a Default Order if moving doesn’t improve its position or enable it to Fire.

One important point is to add a Default Order clause as the 1st clause of the current version: If the enemy has an unprepared AA gun, carry out an Air Defence Order to prepare it. For aircraft, I’m introducing a method within the AI for enemy planes – but not yet shared with my co-designer Nick Fallon, so I’m keeping it up my sleeve for now.

Final denouement: a very close finish, the US just squeaked it.
