I think they fly Brewster Buffalos. OK, they may have upgraded since then lol. But they flew them in World War II. They did real good with them. It gets unfairly criticized when people compare that 1937 aircraft with 1941-1942 aircraft. I like the P 39, and it didn’t fit with our 1942 and later needs, but it excelled fighting the Russians where the air combat took place at lower altitudes as a general rule.
Finnish US Brewster (F2A1) BW-364 is credited with 42 1/2 kills by all the different pilots who flew it.
This quote from Wiki: After evaluation of claims against Soviet actual losses, aircraft No. BW-364 was credited with 42½ kills in total by all pilots operating it, possibly making it the highest-scoring fighter airframe in the history of air warfare.
Another source credits BW-393 with 41 kills. If anybody is good at counting, this site has a list:

The Brewster Aeronautical Company was the ONLY US aircraft company to go out of business during WWII. Problems with crooked management, union strikes and sabotage, and an outdated design led the Navy to take it over in 1944 when it became the Naval Air Modification Unit.
