Thanks, guys...I see your points regarding on-line lag, and I understand the armament disparities in this sim...all good points.
But the best answer came from Vermillion where he differentiated between a planned, level HO and unplanned shots of opportunity. Very good, Verm...and exactly how it is done in real life.
I never deliberately went HO against anyone in the sense of how he described a level, nose to nose, planned attack. But I sure as heck took enough forward aspect shots when the ROE permitted. (In RL, most engagement ROE specify a max of 135 degrees crossing angle for typical close in shots. This is for safety's sake. If you think this is sporty in a WW2 sim, you ought to see it for real, in a jet, when you both are over the mach. Been there, done that, scared the toejam out of myself..more than once!)
'To HO or not to HO' is a complex subject, and not one that be explained away as poor BFM (and the term is BFM, not ACM! ACM is something entirely different.) The other posts raised valid concerns such as fuel state, numerical advantage/disadvantage, etc. Those are all good reasons to consider the HO.
But, given the fuel, time, turning room, and SA, I prefer to BFM the bandit's brains out before I kill him.
It just seems like the right thing to do!!
