A notable series of squad-level historical wargames. They use simultaneous turn resolution ("[[TurnBasedStrategy WeGo]]") and place an emphasis on historical accuracy. The series features an incredibly detailed simulation of ballistics, armor, and penetration, especially as it relates to tank armor; things such as ricochets are fully modeled, as is individual vehicle component damage. The difference types of cover and concealment are also modeled in-game with meticulous detail - rifle bullets can potentially punch right through drywall, for example, and a mortar shell will go straight through a thin sheet-metal roof. The series is also extremely easy to mod, and boasts a robust built-in scenario and campaign editor.
So far, there are six games in the series:
Beyond Overlord: June 1944-May 1945 in Western Europe.
Barbarossa to Berlin: June 1941-May 1945 on the Eastern Front
Africa Korp: 1940-1945 in North Africa and the Mediterranean.
Shock Force: A fictional modern war between the U.S. and Syria.
Afghanistan: Takes place during the Soviet-Afghan War in the 1980s.
Normandy: Beyond Overlord's setting remade in the new CMX2 engine.
!! This series provides examples of:
* AllThereInTheManual: Every single tank, self-propelled gun and antitank gun of the war is painstakingly reproduced, along with each and every variant they had throughout the war. During battles, you can right-click on them to know exactly how much armour they have, how sloped it is along which angle, how much armour penetration you can expect from the gun and so on. On the recruiting screen however ? Well, if you don't want to buy the wrong one, you'd better know them by heart. All of them.
** Anti-Tank, anti-personnel, and daisy chain mines.
** [=IEDs=] in ''Shock Force'' and ''Afghanistan''.
* BreakOutTheMuseumPiece: Playing as the Syrians in ''Shock Force'' will often leave you stuck with such state-of-the-art technology as the BTR-60 APC (first designed over half a century ago) and T-55 main battle tank (ditto). Afghan rebel fighters and tribal militias in ''Afghanistan'' regularly use UsefulNotes/WorldWarII-vintage weapons, along with occasional relics from UsefulNotes/WorldWarI and a smattering of weapons which were already fairly old even then - you'll encounter a lot of 1890s-vintage Enfield and Mosin-Nagant rifles, for example.
* CannonFodder: Conscript infantry, in general, but particularly those poor quality Soviet troops making Human Wave attacks.
* TheComputerIsACheatingBastard: Units occasionally display atrocious path-finding skills, with tanks redirecting themselves half way around the map, rather than wait for the rout ahead to clear. In ''Shock Force'', infantry have the alarming habit of picking the wrong side to enter a building, preferring to run around to the front and into enemy fire instead of using the available, safe back door.
* CurbStompBattle: The entire story campaign of ''Shock Force'', which is about the full force of the US and NATO being called down upon the army of ''Syria''. It's made clear at the beginning of the game that allied forces losing the war is not even remotely within the realm of possibility; the only way the outcome can be affected is in determining exactly how fast and decisive the victory is. Allied forces have both numerical and technological superiority as well as massive amounts of artillery support and total air supremacy.
* EasyLogistics: Somewhat applicable. Infantry never run completely out of ammunition, though once they reach "low" their firepower drops by half, and they can only fire in self defense. Vehicles also never run out of fuel, although they can still be immobilized by a burst tire, damaged track, or destroyed engine.
* GlassCannon: Known as "Eggshells with Hammers" within the community. Notable examples are the Nashorn (88mm [=PaK=] 43 and 15mm armor), the Archer (17 pounder and 20mm armor), the M18 Hellcat (76.2mm cannon and 25mm armor), and many self-propelled howitzers.
** The various Marders would also count, along with most Russian early war Tank Destroyers - the armour of a half-track, the cannon of a heavy tank. Learn keyholing or die. For that matter, you really should consider fixed & towed antitank guns as one-shot weapons too, since the enemy is sure to drop arty or at least direct machine gun fire on their position once they've revealed themselves.
** In ''Shock Force'', Syrian anti-tank missile teams. One well-placed shot to the top armor of a Stryker or Bradley can fireball the vehicle - and you better hope it hits, because that one shot is all you're going to get.
* GodDamnBats: smoke shells, of all things. The computer AI is particularly fond of firing them at your armour, rendering them useless until they are clear of the fog. Of course, that is the entire point.
* MissingBackblast: notably averted. Troopers armed with Bazookas and Panzerfausts can fire from indoors if you order them to. They won't do it on their own, and with good reason: the backblast most often sets the whole building on fire and is quite likely to wound the people firing it. The British PIAT is notably exempt from those rules as per history, since it was less of a rocket launcher and more of a giant spring.
* TheEngineer: Combat Engineers, in particular. Engineers are expensive, specialized infantry. They carry demolition charges, can clear minefields, and are usually accompanied by flamethrowers.
* KillItWithFire: All manner of flamethrowers. In practice, these mostly just rout troops and deny ground.
** Russian troops also pack Molotov cocktails in lieu of antitank grenades (and in some case have special slingshot-like launchers for them that allow the cocktails to be flung at greater ranges than most grenades, although the accuracy is questionable).
* NoSwastikas: Some versions of CMBO refer to the Waffen-SS as "Waffen Grenadiers," a designation that was in reality only applied to non-German SS units.
* TankGoodness: Everything from the M5 Stuart to the single Super Pershing. Assault Guns, Tank Destroyers, SP Anti-Aircraft weapons, tankettes. Only a few obscure, captured vehicles are omitted.
** Shock Force, the only entry in the series thus far set in modern times, includes (with expansions) every single armored fighting vehicle currently in service with the militaries of the United States, Canada, Germany, the Netherlands and the United Kingdom, as well as a whole host of surplus Soviet and Russian tanks and APCs.

* WhyWontYouDie: Inevitably happens when that one particularly resilient, enemy tank runs amok amongst your forces.
* ZergRush: Soviet Human Wave attacks.
