GHPC Early Access has been updated to version 20250212.

This is a regular update, introducing new features, adjustments, and bug fixes.

We've got plenty more in the works for GHPC! As always, you can get additional info by visiting our Discord server and YouTube channel. Links are on the GHPC website[gunnerheatpc.com].


From very early on, it has been our intention to feature four military groups in GHPC: the forces of the United States, the Soviet Union, and both East and West Germany. With this update, at long last, the Bundeswehr of West Germany makes its debut!

Much like the initial debut of the Soviet forces in GHPC, the West German unit set included in this update is limited to only a small portion of what we intend to add to the game. Today we are introducing the Leopard 1A1 family, the German variant of the M113, and West German troops with basic kit. More additions, such as the Marder 1, Leopard 2, and additional West German infantry weapons, will arrive when they are ready.


Four variants of the classic Leopard 1 tank are now available in the game: the Leopard A1A1, A1A2, A1A3, and A1A4. Much like the M60 and M1 series, all of these are armed with a variant of the venerable 105mm L7 cannon and carry a familiar suite of rounds for different purposes.

There are several points on the features of the Leopard 1A1 that deserve explanation.


The Leopard 1 features a unique form of optical rangefinder using the "stereoscopic" method. At first glance, this sounds similar to an optical coincidence rangefinder: the crew's viewfinder is fed by two sight apertures on the sides of the turret, which they focus on the target in order to judge the range. But the operating principle is very different.

A coincidence rangefinder requires the user to overlap (coincide) two images to set the correct range. This is seen in GHPC's M60A1 (where the images are transparent and overlapping) as well as the Soviet TPD-2-49 sights (where the images are displayed as two half circles that must be aligned). By contrast, a stereoscopic rangefinder relies on the user's 3D depth perception. The reticle of the stereoscopic rangefinder is rendered separately in each eyepiece in a way that makes it appear to "hover" in space, far in front of the optic. Adjusting the range setting of the optic will send the image of the reticle "toward" or "away from" the user. When the reticle appears to be at the same distance as the target, "touching" it in space, the range is correct.

Unfortunately, we cannot show a floating reticle in 3D space on a flat monitor, so we've taken some artistic liberty with the Leopard 1 rangefinder. Our depiction of the rangefinder's distance setting relies on two visual cues:

3D reticle with camera sway: The reticle is indeed projected into space, but rather than using your brain's binocular vision skills to convey the depth, we induce some camera sway or "head bob" while the sight is in rangefinder mode. The subtle perspective shifts of various objects in view help reveal what distance they're at. When the range is correct, the reticle will appear to move with the target as one, rather than shifting around over it.

Forced depth of field effect: Since we can't make your eyes see the depth cues on a flat screen, we've added cranked up the focus blur on objects that are not at the current distance setting of the rangefinder. If the target comes into sharp focus, that's a good sign that the distance setting is roughly correct.

The combination of these two visual cues should allow the stereoscopic rangefinder to be useful, while being visually distinct from the coincidence rangefinders on other tanks.


The standard Leopard 1 loadout for the early Cold War numbered 60 rounds total, consisting of APDS, HEAT-FS, and HESH. However, during the second half of the 1980s, the Bundeswehr switched over to a 55-round APFSDS and HEAT-FS loadout, much like what the US Army was using at the time. Due to this change, there is some variation in official standard Leopard tank loadouts from the Cold War.

We have chosen to depict this shift by giving the Leopard A1A4 the updated ammo loadout by default, featuring DM23 APFSDS as its standard dart. The three other variants receive the earlier loadout with DM13 APDS. The customizer will allow you to swap the sabot ammo type in any Leopard A1 variant, though the vehicle will retain the same number of ammo type slots it originally had.


High-Explosive Squash Head (HESH), sometimes called High-Explosive Plastic (HEP), is a brand-new type of ammunition for GHPC. In addition to standard HE blast damage, this round has a rather unique way of damaging armored targets. The head of the round is made of plastic explosive compound, and upon impact with a flat surface, it quickly deforms into a broad pancake before detonating. For homogenous plates of the correct thickness, the shock of the detonation on the outside surface blows off a chunk of armor on the inside, sometimes called a "scab". The armor scab then rips into the interior of the target, damaging it the same way penetration spall would.

Much like real-life HESH rounds, the 105mm HESH featured in the Leopard A1 loadout is most effective against lightly armored targets and when impacting a perpendicular or mildly angled surface. Some amount of angle will make the round more effective, but too much angle will cause it to rapidly become useless, possibly failing to detonate at all. In addition, the armor scab tends to blast off in the normal direction (directly away from the plane of the armor face), so the target's shape will have a large influence on whether you damage anything important inside of it.


The Leopard A1A1 and A1A3 featured a fairly limited night sight system: an active IR sight installed in the commander's position. This sight could only be set for a range of 800, 1000, or 1200 meters. In the daytime, it was uninstalled and replaced with a day sight. In GHPC, the range limitations of the sight are accurately depicted, and using it will clamp your FCS range setting to the acceptable range. The sight is fully unavailable in daylight missions.

With the Leopard A1A2 and A1A4 came an upgrade: the PZB-200 night sight. This passive sight, now using an add-on fixture on the gun mantlet, allows far better image quality and a wider range of distance settings. The PZB-200 in GHPC is represented with a screen border similar to its real display.


The backup telescope sight in the Leopard A1 is unusual in that its zero mark is quite high in the viewfinder. This is done to ensure that the sight will remain usable with the large ballistic drop of HESH ammunition at longer ranges.

Unlike the rangefinder sight, which is limited to a setting of 400 meters and above, the auxiliary sight can be set as low as 0 meters. However, returning to the rangefinder sight with a range setting below 400 selected will reset it to 400.


Continuing tradition, we have a chart showing the differences between the different Leopard A1 variants in GHPC.

An asterisk (*) indicates that the item is not strictly attached to the variant in real life but was chosen to reflect contemporary changes to the West German Leopard fleet at roughly the same time.

You can use any variant of the Leopard A1 in any mission after successfully completing it at least once, using the mission customizer menu.


Like several other NATO member states, West Germany used a local variant of the M113 APC during the Cold War. Their version of the M113A1 was fitted with German lamps and a German smoke grenade launcher rack. Its main armament was an MG3 medium machine gun on a special mount that allowed high elevation angles when necessary. The M113A1G is featured in the two new Eastern Road missions and can also be used in any mission with an APC slot in the customizer menu.


There are some situations where the standard 70-round APDS belt for the Bradley's 25mm gun feels like it's not enough to deal with the amount of enemy light armor. In real life, crews had the ability to load their armor piercing belts in the large bin if they needed to. To reflect this flexibility, we've added a special "alt" variant of the M2, with the ammo load swapped so it carries 230 ready rounds of APDS and 70 of HE. The mission Crossroads Screen now features this variant by default, but you can use it in any mission that allows IFVs to be swapped in the customizer menu.


Our map designers are working on a smaller, more dense map to use for new missions. Though some assets in the map are still a work in progress, we've decided to release it in this update. Two new Leopard-focused missions entitled "Table Salt" are available in the Eastern Road section of the Instant Action list.


As part of this update, we have modified several existing missions to add troops:

• Casual Cleanup
  
• Keen Kestrel
  
• Lethargic Liberty
  
• Slow Raid
  
• Fog of War
  
• Steel Wedge

Soviet infantry, armed with AK-74 and RPG-7VL, are now available in GHPC. They will appear in any missions that include infantry and use Soviet forces by default. You can also select them in the customizer menu for the infantry slot in any other mission where that is available.

Note that with the addition of Soviet troops the East German anti-tank rifleman loadout has also been altered to use an earlier variant of the PG-7 warhead.


West German Bundeswehr infantry are now available, armed with G3A3 rifles. They feature in the Table Salt missions, but (just like the Soviet troops) they can be used in many other missions with the customizer feature.

As of this initial release, the West German troops use the LAW as their light anti-tank weapon.


Most infantry weapons now have animated reload sequences. This has no gameplay impact, but it looks cool, which is very important in its own right.
