Good point, although there were (rather amazingly) some Sturmovik kills and Stuka kills too, especially with the D model that had the 20mm cannon. D3A Vals got a few victories too. So did Blackburn Skuas.
But the SBD does seem to stand out as a pretty good brawler as bombers go. It probably had the best record for any single engined bomber in air to air combat. It had the maneuverability of a dive bomber with a rather exceptionally sturdy and well protected construction of many US Navy planes. Part of what was needed was better training - the scout squadron SBD pilots got some air to air gunnery training but the dive bomber squadron pilots didn't so much. Swede Vejtasa himself said that his colleagues in that same action got killed because they didn't know to make hard, high G turns (and later, to do slips etc.) when first attacked by Zeros, that is how he evaded the shooting passes. IIRC he had three colleagues shot down in rapid succession at the beginning of that fight he was in.
The twin nose guns on the SBD were hard hitting and sufficient to kill Japanese single-engined aircraft. That meant the SBD could do head on passes if it could turn to face an attacker. The SBD could also turn sharply enough to evade attacks at least for the moment. This got a lot harder when multiple planes were attacking (with one able to attack if you turned left and another if you turned right). In practice, the SBD proved sufficient as an "emergency fighter" against lumbering B5N torpedo bombers and slow E-13 float plane scouts, and maybe F1M "Pete" floatplane fighters, but not much else. It wasn't really fast enough to catch G4M Bettys, or nimble enough to catch D3As (except on a couple of occasions). The Zero completely outclassed it and even aces like Vejtasa were terrified when they had to engage Zeros.
