Some points about cover and stuff

Highlights:

2:28 Tommies in "Heavy Cover" losing to Sturmpioneers in "Negative Cover", this is actually misleading.
The Tommies are in Heavy Cover only insofar as it relates to units engaging from the other side of that cover, cover is generally directional. A unit with the green shield can still be in negative cover, since that road they're fighting on is basically a paintbrush of negative cover. The Sturmpioneers on the other hand are taking fire mostly on the one model who is in fact behind a rock wall.
Just because a unit has a certain color shield saying cover/nocover, doesn't mean anything. Cover is applied per-model, and directionally.

You do have to account for scatter as well, if there are infantry models behind a Heavy Cover model, those infantry models might be hit by stray shots. This happens a lot more than you might think.

Bear also in mind that where the shot "looks to be hitting" is completely irrelevant, the animations aren't necessarily tied to in-engine results. Sometimes a shot looks to be hitting an object and yet it does damage. There are exceptions to this however - AT Guns, Tanks and Projectile Weapons are the inverse to this rule. Snipers also have a few oddities to them:
Tell a Sniper to shoot at a building (which has a garrisoned unit inside, so you just right-click) and the Wehr/Soviet Snipers will do just that - shoot at the squad inside. Tell the Brittish sniper though to do the same thing, and he will literally shoot the building itself often ignoring the infantry models within.

4:48 Tommies blew up the Kübelwagen. For the prior 20 seconds the Kübel seemed to not take any damage. Remember above I said to "ignore the animations"? This is why: Just because a Vehicle "gets hit on the side / rear" doesn't mean this in fact happened.
Vehicles in CoH2 are not 3D, they're 2D. Instead of a Kübel imagine a flat line. 50% of the unit is Rear, 50% of the unit is Front.

Where the unit gets hit on is determined by a dice roll proportional to the angle presented, any increase of 90 degrees results in a 25% increase/decrease to front/rear hit chances respectively if you're rotating your rear away from the enemy, and this is inverse when you're rotating the front away from the enemy. If a shot "Hits the rear" of the vehicle it still counts as a "Frontal Hit" unless the game gives you that big red "REAR HIT!" event text. The Kübel's armor is such that trying to take it out from the front will take you a while, so what's relevant is where you're hitting it, not if you're "penning", since the penetration chance is that low from the front.

5:35 Sturmpioneers run over "Negative Cover" and engaged a Tommy squad in "Heavy Cover", here's a wonderful thing about cover that is often overlooked: Under 10 range, Cover no longer applies. Thus, the Sturms running over that small distance between the house and the wall did suffer damage, but they were also dealing lots of it while moving (sturms have a relatively high 50% accuracy while moving). The Tommies in "Heavy Cover" had no more protection than they would've in Light or No Cover.
Ironically had the Tommies not been "buffed" out of cover and had their in-cover bonuses lowered commensurately, they would've easily taken out the Sturms. But, it stands that Tommies' in-cover bonuses are negligible if within 10 Distance from target, since as pointed out above, <10 Distance Cover does not apply.

this is just an ordinairy pridepost

Nice game knowledge. GGWP
