Your very arogant aren't you Ack-Ack?
As I said, please inform me as to what else it would take to make a sherman DD besides having it look like a sherman DD, and function like a sherman DD? The fact is it doesn't matter if the suspension is the one the sherman DD used, simply because it is irrelivant. No one will ever see it, no one can ever call HTC on it, no one will know, and (most likely) no one will care. If something looks like a helicopter, and flys like a helicopter, then it is a helicopter regardless of wether it uses a planes prop for the tail rotor, and has a car's engine.
I wouldn't really call the fact that the LVTA4 could fire AP rounds "widely known". In fact, it seems like you wouln't know that unless you were studying it; its not something that will be related to anything else. You're not going to see something like, "The 76mm armed shermans were introduced to compensate for the poor armor penetration of the 75mm armed shermans. The cannon's armor penetration is just slightly superior to that of the LVTA4..." on a web page.
Ack-Ack, you aren't the one who gets to judge wether or not the sherman DD is a valuable use of resources, hitech is. And your suggestion of giving the LVT some AP rounds would likely take just as much time as adding the skirt, rudder, and props to the M4. They would have to find the balistics of the weapon, see if its muzzle velocity was affected by firing AP rounds as opposed to HE rounds, they would have to model the shell drop, velocity and whatever else they use (unless of course they have a basic cannon template, and just give it the specs of the gun they want, and then change the visual stuff).
And I believe I WAS taking it up witht he person who made that remark. Not all of my post was directed toward you, just as the planets don't revolve around you.
321BAR, I'm fine with loosing, as I likely will. I know he's better than me at fighters; I just wana see how long I can evade him in my 190A5.
