The '''2.8/2 cm S.Pz.B.41''' (Full designation: ''schwere Panzerbüchse''; English: ''heavy tank hunting rifle'') is a German anti-tank gun that utilizes a squeeze-bore principle for the projectile's kinetic energy. The squeeze-bore principle has a varying barrel diameter from the chamber to the muzzle, which "squeezes" the projectile as it propels through the "bore" in order to obtain a higher muzzle velocity. This results in the strange calibre naming for the weapon, which starts at 28 mm diameter at the chamber that steadily decreases to 20 mm by the muzzle end.

The 28/20 mm S.Pz.B.41 on the Sd.Kfz.221 (s.Pz.B.41).

Description

The 2.8/2 cm S.Pz.B.41 (Full designation: schwere Panzerbüchse; English: heavy tank hunting rifle) is a German anti-tank gun that utilizes a squeeze-bore principle for the projectile's kinetic energy. The squeeze-bore principle has a varying barrel diameter from the chamber to the muzzle, which "squeezes" the projectile as it propels through the "bore" in order to obtain a higher muzzle velocity. This results in the strange calibre naming for the weapon, which starts at 28 mm diameter at the chamber that steadily decreases to 20 mm by the muzzle end.

General info

The 2.8/2 cm S.Pz.B.41 is hindered by the fact that it only has one type of ammunition available in-game, the Pzgr.41 APCR ammunition. However, the squeeze-bore principle does indeed propels the ammunition at an extremely high velocity of 1,400 m/s

Comparison with analogues

As of Update 1.87, the S.Pz.B.41 is a one-of-a-kind squeeze-bore weapon in the game that presents high velocity and penetration for the calibre.

A captured S.Pz.B.41 in the hands of an Englishmen during the North African campaign.

A similar weapon that retains a "lightweight" construction and small-calibre shell is the Italian Fucile Controcarri S Mod.39 anti-tank rifle inside the L3/33 CC.

However, in terms of a weapon that have similar penetration power as the S.Pz.B.41 is the British 40 mm OQF 2-pounder, with the Shot Mk.1 APCBC/T that can penetrate 96 mm at point-blank range at perpendicular armour. The firepower parity at such a difference of calibre is testament on just how much faster the S.Pz.B.41 shell is going due to the squeeze-bore princple.

Usage in battles

Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against the main opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.

Pros and cons

Summarize and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.

Cons:

History

Examine the history of the creation and combat usage of this weapon. If the historical reference turns out to be too big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article.

Media

An excellent addition to the article would be a video guide, as well as screenshots from the game and photos.
