The single bullet statement is only meant to illustrate how, with a liquid cooled engine, a single well placed bullet in the cooling system can disable a fighter. Obviously a single bullet in a single seat fighter's pilot's head can bring down any aircraft. A survey of both American and British pilots at the fighter meet in Pautuxent River, Md. in 1944 showed that 79% named the R2800 as the engine which inspired the most confidence. 17% named the Merlin.
I'm sure there are a lot of single point failures in a R2800 that is suseptable to a bullet; oil pumps, oil lines, oil coolers, fuel lines, fuel pumps, even a lucky shot into one of the jugs could possibly cause failure of the engine. It was a tough engine and less complex and less vunerable than the Merlin, just not totally bullet proof.
