I'm not really sure what the issue here is regarding machine-guns; I have a copy of RV open in front of me, and I see bow machineguns on my Tigers (both types I & II), Panthers and Mk IV's. If the original poster feels strongly on adding more machineguns to tanks (and I have yet to try this for machineguns, but I believe it will work because I have done it for other weapons), you can in fact mod existing systems within the RV module. The dat files are locked against adding NEW weapons to the game. You are not actually adding anything to the game by locating the Tiger tank in the vehicle.dat file and adding to it an additional machinegun, because it uses an already existing weapon system from the weapons.dat file and existing load from the loads.dat file in the game. So if you really feel strongly that something needs changing or adding, you could do this yourself.
While I cannot speak for Rich Hamilton directly, it appears there is simply some confusion on what was discussed. Rich's comment regarding how machineguns are in some instances rolled into other values of weapons or tanks is based on the fact that for example, you don't find the 'coaxial machinegun' nor 'turret roof mounted MG's' represented in most instances, unless that weapon was the main armament of the vehicle. So yes, clearly Rich spoke a fact; some machineguns HAVE been combined into a grouping or calculated into some other aspect of the vehicle. Still I don't see what the issue is, seeing as I am looking at bow MG's on said tanks - however, if there are inconsistencies or missing machineguns, this is an extremely minor issue and not code or programming related. In plain English that means in itself, it is unlikely to generate a patch.
The Eagle Strike title does not have limitations on the various dat files; in other words, you can mod to your hearts desire.
