Dive toss bombing

So you spawned in a bomber (or PBJ) in an arcade ground forces battle and see no chance surviving the many red interceptors that spawned as well? I get ya, particularly the Wellington is of very little use in such a situation.

There is one tactic that may still allow you to kill red tanks in that sortie, though: Dive toss bombing.

You retract the flaps if they're lowered (which they often are for no good reason) to reduce drag. Pitch down the nose to pick up speed. Once you're fast and close enough (based on experience), you pull up again into a not too steep climb. (Side benefit: The aim of fighters will be somewhat degraded by this manoeuvre.)

There will be the bomb impact circle symbol on the ground well ahead of you. Much farther ahead than if you were flying level. Maybe it's obstructed by your plane, in which case you should switch to "F4" view.

Now preferably aim at a group of red tanks that are bunched up or depicted in a (vertical) line. Quickly drop your bombs on these.

Next, press "J" to leave you bomber ASAP and resume playing tank before your tank gets roasted. Your bomber is of no use any more.

The bombs may very well be in the air for so long (doing their whining sound) that they'll detonate instantly on impact. This means stationary tanks won't escape by driving away, which partially compensates for the inaccuracy of the hurried tossing.

It's advantageous to be a skilled War Thunder plane pilot, even in War Thunder ground forces!

(Toss bombing was originally meant to allow subsonic aircraft to deploy powerful nuclear free-fall bombs without damaging themselves too much. The tossing increases the distance and the time till explosion.

Toss bombing was also used during the Falklands War for a low risk attack of Sea Harriers against the well-defended Port Stanley airfield. It can also be used to accurately attack a target with a guided bomb, as shown in the illustration above, if only the guidance method doesn't depend on the bombing plane itself having a line of sight to the target during the bomb's terminal approach to the target.)
