Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

Usage in battles

The LB-1 is very similar to the guns on T-54, but lacks APDS or HEATFS. The gun also has a similar playstyle to the 122 mm, but with better penetration and better reload. It has less HE filler than the 122 but is still usually able to one-shot opponents from the side.

Pros and cons

Pros:

• High penetration
• High damage

Cons:

• Long reload time

History

Examine the history of the creation and combat usage of the weapon in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/ History" (example: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></ref>, as well as adding them at the end of the article with <references />.

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
