== Usage in battles ==

''Describe the tactics of playing in the aircraft, the features of using aircraft in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).''

=== Pros and cons ===


'''Pros:'''

* Rather powerful bombload of one 500 lb bomb or two 250 lb bombs for the battle rating
* 4 x 7.62 mm MG is decent firepower for the battle rating, allowing it to effectively damage/destroy aircraft if needed
* Great over-the-nose visibility makes leading very easy in Simulator
* Engine does not overheat quickly
* Has a rear gunner with a 7.62 mm MG for self-defence

'''Cons:'''

* Extremely poor speed for a monoplane, cannot even catch I-16s quickly
* Very slow energy retention
* Is quite a big target
* Does not have any armour protection
* Does not have reflector gunsight, meaning you cannot move the pilot's head in Simulator or the reticle will not align
* Overall aircraft responds slowly to aiming adjustments, making it hard to put a solid burst into a manoeuvring target
* Bombload is quite poor for an aircraft of its size and role, the Hawk III carries the same payload while being a lightweight biplane

== History ==
An initial order for 30 two-seat V-11Gs was placed by China before the end of 1935. This was followed by orders in 1939, for two versions (the V-12-C and V-12D) of the more powerful V-12 variant. The majority of these were planned to be assembled from kits at the Central Aircraft Manufacturing Company factory at Loiwing near the China-Burma border, and while the first batch of 25 V-12-Cs were completed successfully, the factory was heavily bombed just after assembly of the first V-12-Ds commenced. This resulted in the part built airframes being evacuated to India, where it was planned that the aircraft be completed at the Hindustan Aircraft Limited factory in Bangalore. However, after a few were assembled, production was stopped as the factory was diverted to more urgent overhaul work.

The V-11s and V-12s were used as light bombers and achieved some success, including a mission to bomb the Japanese held airfield by 4 aircraft at Yuncheng on February 5, 1939, by the 10th Squadron of the Republic of China Air Force, before the aircraft were withdrawn from bombing missions to training and liaison duties in 1940.

== 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 ==
The Martin Model 139 was the export version of the Martin B-10. With an advanced performance, the Martin company fully expected that export orders for the B-10 would come flooding in.

The Army owned the rights to the Model 139 design. Once the Army's orders had been filled in 1936, Martin received permission to export Model 139s, and delivered versions to several air forces. For example, six Model 139Ws were sold to Siam in April 1937, powered by Wright R-1820-G3 Cyclone engines; 20 Model 139Ws were sold to Turkey in September 1937, powered by R-1820-G2 engines.

On 19 May 1938, during the Sino-Japanese War, two Chinese Nationalist Air Force B-10s successfully flew to Japan. However, rather than dropping bombs, the aircraft dropped propaganda leaflets
