Description

The 25 mm M242 Bushmaster is a chain cannon used on various vehicles such as the Bradley series of IFVs and the ADATS.

Vehicles equipped with this weapon

General info

Tell us about the tactical and technical characteristics of the cannon or machine gun.

Comparison with analogues

  • MK 30-2/ABM (30 mm): A 30 mm German autocannon with a similar rate of fire
  • 2A42 (30 mm): A Russian autocannon with similar penetration and damage but a higher rate of fire than the M242
  • 2A72 (30 mm): A Russian autocannon with similar penetration, damage and rate of fire
  • Oerlikon KBA B02 (25 mm): A 25 mm autocannon of the same calibre with a higher rate of fire

Usage in battles

The M242 Bushmaster can handle and defeat most of the opponents that it faces within its BR, though certain MBTs and heavy tanks will be difficult to defeat as the autocannon does not have enough penetration to effectively kill these heavy tanks. Usually flanking manoeuvres are required as most MBTs at this tier lack in side armour, where the M242 can easily punch through the armour, though certain MBTs such as the Leopard 1 can be penetrated from the front. Be aware of Soviet/Russian main battle tanks as they have up to 80 mm of side armour, where the M242 cannot penetrate the side unless you have M919 APFSDS, which is only available on the M3A3 Bradley. The M242 can also defeat air targets as well, although due to the low fire rate of 200 RPM, defeating jets are going to be difficult from their high speed. The ADATS does have a modified M242, where it can fire at 500 RPM and having a slightly easier time killing jets. Defeating helicopters are easier though as they aren't that fast, and easy to kill if they're going on the attack run in the battlefield.

Pros and cons

Pros:

  • Access to APFSDS (only for the M3A3)
  • High rate of fire (ADATS only)
  • High ammunition count

Cons:

  • Slow rate of fire
  • Tends to overheat easily

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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 />.
