Nicknamed the ‘fork-tailed devil’ by the Germans this versatile and sturdy American fighter is a legend. The nose arrangement of the guns makes it deadlier at greater ranges when flown by skilled pilots.

Banking, with your wings vertical to the ground, is suicidal when an enemy plane is on your tail.
The P38 is very accurate, try to engage enemy fighters from afar!
Concentrate on eliminating or discouraging enemy airpower. This will leave the skies open for you to ravage the enemy ground forces.
If you're damaged and have an enemy on your tail, try dropping a bomb and turn off engines to make it look as though you've bailed out.
Refrain from destroying anti-aircraft placements. They re-spawn with full health and worse yet, full munitions.
Encourage your team to spot enemy tanks for you, often they will respond positively and you can encourage more of this behavior with a bomb in the back side of some enemy tanks!
Aim for and watch for pilot hits/kills, this can quickly take down an enemy plane whilst wasting very little ammunition. Although, you will receive less points for not destroying the enemy aircraft.
The hull & turret armor is still pertinent to bomb damage, line up your shot; you might just take out a panzer with one hit.
Approaching enemy anti-aircraft weapons quietly (engines off/slowed), from up high, far away, and directly from the sun (they have to look into the sun to see you), gives you a distinct advantage. A few blips from your machineguns, and you're good to go.
