Usage in battles

As a bomber, the Martin 139WC does the job well. It can easily reach bombing points before interception and can damage a base with two 250 kg bombs, and can then turn away and return to base to rearm. If enemy fighters are at altitude, consider using clouds for cover, or entering a shallow dive towards friendly fighters, or the airfield.

This aircraft works very well defensively and can be very effective when flown with a squadmate. As this bomber is very manoeuvrable, it can out-turn most enemy fighters, but lacks the firepower to deal with them effectively, it has no fixed guns and is only equipped with .30 calibre machine guns, and controlling them manually in a dogfight isn't really a viable option. But when playing with a friend, the Martin 139WC can engage a fighter, and while manoeuvring, can draw the enemy into a low energy state, making it a very easy target to take out.

On your own, you can still comfortably dogfight one-on-one with most German and Italian monoplane aircraft, but if this fight is away from friendlies, another enemy fighter could engage with you, and being such a large target, a 2-on-1 fight likely won't go in your favour. As you are a big target, and with two enemies around you, one is likely going to take out a critical component sooner or later.

Try diving towards friendlies before engaging in a dogfight, the closer you are to your allies, the more likely it is that they'll come to your aid, the further away you are, the more likely it is that an enemy will join the fight instead.

If there are no enemies around later on in the match you can attack light ground targets by manually controlling your nose gunner, just make sure to watch out for any trees or ground hazards as there will be a delay before you can switch back to direct control of the aircraft.

Pros and cons

Pros:

  • Very manoeuvrable, has an impressively high turn rate for a bomber
  • The frontal gunner, while only having a .30 cal, can be used as a manual weapon if you keep the front of the plane on an enemies tail, or for attacking ground targets
  • As it's a less well-known aircraft, enemies may not know how to effectively fight it
  • It can easily take fire from machine guns on the wings, and in general is fairly survivable
  • While having limited fire arcs on the rear turrets, they cover a wide area and can surprise enemies that don't know they're there

Cons:

  • It's a large target, and even though the critical components are hard to hit individually, the large wings and tail will accumulate damage over time
  • Maximum bombload of 2 x 250 kg bombs is not a lot
  • No armour protection at all, leaving it vulnerable to even small-calibre MG.
  • Despite its comparatively good speed, most Axis aircraft can catch up to it easily
  • Rear gunners have a slightly restricted field of view over the tail, where the gunners can't fire

History

Describe the history of the creation and combat usage of the aircraft 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 vehicle and adding a block "/History" (example: https://wiki.warthunder.com/(Vehicle-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 />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).

Media

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