Oh yeah, and the strike factor will also take into account better
shells later in the war, and various other additions such as squeeze
bore adaptions to weapons, the raw data for the 2 pounder squeeze
bore on the Tetrach, for example, gives it a strike of 9 rather than
the 7 for the early war weapon.
Equally, if anyone enjoys trig and wants the formulae for armour
classification and strike factors I can let them have that and they
can work out there own stuff, and even let me have a copy if they're
doing the Ruskis!
