Doing the geek thing, I was working on a database modeling or reflecting the game and the question of Tracers came up (in my mind)...
According to this (from the web), it appears as if Tracers were more a liability than an asset:
It was a common practice on fighter planes to load every 5th round with a tracer round to aid in aiming. That was a mistake. The tracers had different ballistics so (at long range) if your tracers were hitting the target, 80% of your rounds were missing. Worse yet, the tracers instantly told your enemy he was under fire and from which direction. Worst of all was the practice of loading a string of tracers at the end of the belt to tell you that you were out of ammo. That was definitely not something you wanted to tell the enemy. Units that stopped using tracers saw their success rate nearly double and their loss rate go down.
Aside from the obvious question/response, do you use tracers or not?...Does the game model tracer ballistics differently than standard rounds?
I doubt it (too much complexity for no benefit in terms of game play)...
Now as a bomber pilot (who guns for himself 99% of the time)...I find tracers at times great to have, and other times a serious detriment.
They are beneficial on long deep bomber runs at altitude to send a clear message to an interceptor before he is in gun range...THAT I AM NOT ASLEEP...proceed with extreme caution...
On the other hand, sometimes I want them to think I am asleep before they figure out that "Ma Duece" cleaver is descending on their canopy
Tracers?
On or off?
Ballistics same or different?
Oh and one last thing/question...if a guy has his tracers off...do you still see his muzzle flash when firing..?
Out
Oneway
Oops...one more rather obscure question...if your game options have tracers turned off...and you join a bomber pilot who has tracers turned on...whose setting overrides for the gunner? In other words, would the rounds of the gunner-observer be tracerless, and the rounds of the pilot be tracered? (Did I mention I was a geek?)
