Ok so first you start out by mentioning another sim (its like talking about your girlfriend to another girl)
So kind of a backhanded dis at HTC
And then you want something that by your description, we don't even know if it was used in WWII.
Or if it was when, no specifics on how much weight it added, etc.
And now your wondering why people are raining on your parade.
You might want to try citing historical usage for this kind of thing.
What theaters was it deployed in, when, who was it used by.
And give your references, as many are NOT as good as they might seem.
Some are just plain wrong. A picture is always good.
In short, you want something, right, so do the work first.
