... and anti-building capability. Kind of implies anti-personnel capability minimal.
That's how the Germans and Russians used the Panzerfausts during the Battle of Berlin. The Russians had captured large stocks during the German retreats when they pushed past Warsaw, most likely at HASAG branch factories in Poland, which used to be run as slave labor facilities, if I am not mistaken.
If hollow charges hit walls, then the speed/might of the jet stream (8000 meters per second) created by the explosion (which was then followed by the plasma stream, which was a mix of the disintegrating tank armor, the inner metal lining of the Panzerfaust cone and - in some shaped charges, usually in post-war shells - sometimes even an additional metal penetrator/rod) probably removed one or another brick, so that a pretty small section of the wall could be removed through the sheer speed of the process, but then the soldiers needed to use additional force (hands, tools, hand grenades, feet, rifles), most likely.
Technically, the force of the explosion focuses on a pretty small point:
Face-hardened steel acted differently than a wall, of course, the hole created by a Panzerfaust was pretty small, actually, the impact area was only ~ 50 mm in diameter (1.96 in?). The pic below shows a Sherman tank that was knocked out by a Panzerfaust, the scale on the armor seems to indicate a hole of somewhat over 2 inches in diameter. As you can see, some of the shaped charge's beam particles scratched the armor's surface (in the middle of the pic), this could be the result of a slighty angled shot, but it's also possible that the warhead had hit squarely and that then a fraction of the beam particles could "escape" near the hole (check the square part of the armor, it protrudes from the rest of the side armor), as the warhead cone had a width of 149 mm :
Since the Panzerfaust 60 and 100 could pierce through 200 mm of face-hardened tank armor, it also proved to be ideal to penetrate (some) bunkers. The German Army's modern Panzerfaust 3 can penetrate hardened/reinforced concrete bunkers with thicknesses from 30 cm to 70 cm (depending on type of round) and up to 900 mm of tank steel, regular concrete will be penetrated up to a thickness of 1.6 meters (with the bunker buster round, I suppose).
I can't find a reference for the WW2 Panzerfaust's performance against bunkers and walls, but I just found a reference to a field test of the German Bundeswehr, conducted with their light Panzerfaust (with DM 22 HL round):
The round created a 15-cm wide hole in a brick wall (with a thickness of 28 cm), and a 10-15 cm (width) hole in a (modern german) hollow block wall (where the hollow blocks either contain air or - sometimes - light insulation material). Obviously, both types of walls were fully penetrated.
When used against a concrete wall, the DM 22 HL round created a hole with a width of 3 cm, and 30-cm concrete walls were fully penetrated. The DM round contains a penetrator rod. When used against a brick wall, the penetrator of the round got stuck in the wall on the other end of the hallway, which was 8 meters away. The same happened to the penetrator of the round that had pierced through the concrete wall, it got stuck in the wall on the other side of the room.
None of the tested walls collapsed or lost stability.
In WW2, quite a few buildings (say in villages, suburbs) were half-timbered houses, walls would often consist of a mix of clay and brushwood, or plaster and wood, along with bricks at the base of the building or as outer walls (with probably only 1 layer of bricks). I could imagine that it was pretty easy to tear down such walls after they got hit with a PF.
Hollow blocks came up in the 1850s (British patent from 1850) and may have been used in Berlin's suburbs and in smaller bldgs in the city quite often, but the bulk of the appartment buildings inside the city may have been built with bricks. It took some more work (or hits with several PFs) to create entry points in those hollow block walls, most likely.
In older buildings (18th/19th or early 20th century bldgs) the mortar between the bricks was old and brittle, so it was probably easier to use the Panzerfausts on such walls.
Still, I wouldn't be surprised if the Germans/Russians needed to fire several Panzerfausts or lob one or another grenade through the hole created by the PF, to create an entry point for the squads. If an enemy soldier was hiding behind the wall, and if he got hit by the beam, he was toast, most likely. But spraying particles propably had the potential to incapacitate a soldier hiding near the impact point, already, though.
I used my example in my previous post, where I described the penetration as "liquification", as this is the easiest way to explain/visualize the tremendous speeds that are involved in the process, and how a seemingly very hard material (ie. face-hardened tank armor) reacts if it's exposed to such extreme pressure (8000 meters/second on a very confined area/part). The material doesn't actually liquify, but it's easier to understand what forces are involved if they hit within a 2-inch circle.
Quite a few ppl describe the plasma beam as ultra-hot beam that burns through the armor, but that's only half true, because the jet stream creates a pressure of 10 million kg per square centimeter and this pressure creates a temperature of 8,000° Celsius which will melt/remove the armor at the impact point, and the high kinetic energy of the jet stream then creates a metal beam consisting of the particles (remnants) of the melted armor and of the rest of the metal lining in the warhead's cone. The beam will then enter the vehicle, and it will pull (additional) splinters and the mentioned particles inside. After exiting the entry "tunnel", parts of the beam may lose their integrity, means (hot) splinters may "spray" and even ricochet on the inner walls and may then hit an ammo rack and ignite one or another tank round.
The splinters and particles have the potential to hurt or kill crew members, but the rest of the beam still has plenty of kinetic energy, so that it will proceed to pierce through pretty much everything: crew, shells, devices and appliances, etc., but in a straight line only.
There are quite a few pictures where you can see Shermans or Panthers with Panzerfaust/Bazooka entry points on one side and exit points on the other side, and where the beam (or spraying particles) may have hurt or killed a crew member or destroyed a radio, but where it had not hit any other crucial part of the tank, let alone ammunition, before it had exited the tank hull on the other side.
