I have no desire to be arrested should I blab and go back to the UK for a visit, even though I am now a US citizen. The Brits take their secrets pretty seriously but I also have no intention of sharing anything that may aid some scumbag terrorist somewhere in figuring out a way to penetrate the armor.
On another note, the mil is an angular measurement and is very simple to work with, if you understand metric measurements. One mil subtends 1 meter at 1000 meters with 6400 mils in a circle. So if you are calling in arty and you are 10,000 meters from the firing point, need the POI to shift 100 meters forward and 200 right, s'real easy to call that out. Compared to seconds, minutes and degrees at least!
I know what you are saying about the armor plate, but there's more to the equation than just the plate. And with that I will not go further. Lastly the turret on an M1 tank has been cracked at least twice by the Army. What with, I won't say (you probably already know).
There is a totally new MBT in the works. The drive trane will come in cheaper, and probably be better. (been finished for about six or seven years). The hull is similar in design to what we are using right now (nobody really knows what it looks like), as the parts fit all M1 series hulls and the new hull. But there's also talk about something totally different in the design pool. I will not say, but trust me it'll change the game like nothing we've ever seen before. The work on the main gun is done, and the turret concept is probably finiahed as well.
You are correct about the "circle", but they have it pegged even tighter than that with the addition of some variables to allow them to split a mill without moving the barrel. There's some new stuff in the pipe line that will allow the gun crew to split a mill in segments that will probably end up being in the quarter mill area. The stuff has been tested and the results were stunning to say the least. We saw far more range and much better shot to shot consistencey than we've ever been able to do in the entire history of artillary. The secret is so simple that it makes us look stupid! I still don't see them doing much smaller than fifteen arc seconds without a better hull design (flex has become an issue), and a better way to lock the hull into a single position. But twenty five miles is easilly in the picture if not thirty with a 155 howitzer. Then we will have to finally give the users better maps! Maps the will grid much tighter and more accurately. Right now that's a major problem, as two thirds of the maps used are suspect. What's really interesting is that with the new stuff that old 175 gun is looking far better all the time.
