The Munitions resource for grenades, artillery fire missions and the like kinda makes sense instead of mana, until you realize your troops never run out of ammo for their main weapons and you can later get artillery in the game that uses cooldowns to limit their ability to fire instead of requiring munitions.
The Munitions cost for an American frag grenade is only 1/8th of a Howitzer barrage they can also get. As one can see, it doesn't really add up.
Some of the Munitions abilities (like the Riflemen squad's Suppressive Fire and the Recon Section's Sniper Shot) have the units firing the exact same ammunition they use in regular fighting.
Isn't this self explanatory? The suppressive fire ability makes everyone shoot faster. The Recon's sniper doesn't ever shoot unless you use the ability, as a penalty for the upgrade. Similar explanations can be given to the "button" feature the Bren gun offers, etc.
What's with all the Osttruppen in 2? These guys were sent to guard the rear and perform anti-partisan duties, weren't they? So why do they do the jobs that German troops should have been doing, and why show they show up as far west as Berlin?
They were supposed to be yeah. But when the front got fluid, the distinction between "guarding the rear" and "fighting on the front" could get rather blurry. Furthermore, a number of foreign troops wound up fighting with the SS all the way to the end. Indeed, something like half the defenders of the Reichstag were natives of France.
Panzer Elite infantry will sometimes talk about how they're not the SS, which makes a lot of sense, since both the SS and the Panzer divisions wore black uniforms and the Allies as well as occupied countries often confused the two.
However, this is contradicted by the fact the Panzer Elite ranks for multiplayer actually correspond to that of the Waffen SS.
The Arbitrary Headcount Limit isn't really arbitrary. Historically speaking, having more soldiers in your force than you had resources for (Russia's problem in World War 1 and to a certain extent, fuel wise anyway, Germany's problem later on in World War 2) is very bad, which is why you get an increase in pop cap when you control more territory, which gives you more resources.
Upgrading to flamethrowers increases the rate at which Engineers/Pioneers get suppressed. Upgrading them with flamethrowers adds big flammable tanks to their backs...
The British lieutenant's appearance may ring a bell. He wears the same red berets as the glider commandos.
It only takes two demolitions charges to collapse any single bridge. Why the British and Americans use four is either a matter of balance or them making very sure the bridge goes down.
When enough wounded Volksgrenadiers are taken into a medic station, they come back out as a squad of Grenadiers, the regular Wehrmacht infantry unit. They have seen real field experience and aren't "Citizen Soldiers" anymore; they're experienced and professional soldiers now.
