I take it in order to calculate the armour values for these monsters all I need to do is find the averages for the front sides and back (Turret and chasis respectively) and then work out the angles of the armour slope. Any idea as to what they might be?

The way I do it is I calculate the different slopes and thicknesses like

Upper Glacis 100mm @ 55 degrees = 281 mm effective
Lower Glacis 65mm @ 40 degrees = 106 mm effective

281+106 = 387

387/2 = 193.5

So effective total frontal thickness is 19cm.

Of course this all presupposes that both glacis angles are of equal height. I really need to do some measurements of actual tanks and suchlike to find the proper ratios.

But I do like this system, because it allows me to represent the changes in the JS-2s frontal armor as time goes on

Excellent work Mark. I have added the icons in now so I am most greatful for this data. The new units should be in-game shortly.

[RecruitMonty]

Ok, I am increasingly thinking that the subordinate OOBs, those which would be regions within the empire or those still part of the Allied Remnant, should just have all of their real world units cut and have the bulk of their units, formations and so on tailored to the Imperial or allied line. What do you guys think?

How should I go about this. Just gut the OOBs or replace things systematically to cut dowwn on picklist work?

[PlasmaKrab]

Think you can do a bit of both? What would be the room allowed by Imperial authorities to local manufacturing and design? For those countries that are going to be integral Imperial provinces, I'd suggest going for the "official" imperial pack, or maybe some Warsaw-Pact-style variations (with more or less variation depending on the freedom allowed for said country, and local initiative.
Allied Remnant countries can have a more patched-up kit IMHO, at least for the early years. Look at the early Israeli OOB for similar results given by similar context.

~~#Time for another update#~~

Here we have some Helicopters for you to look at and play with. Introducing the: Do. 205 (a grey and elongated version of the Huey), The Kormoran, again it will look familiar to you but it is slightly different (it is also jet black, looks more imposing that way) and finally the Kaiser, this you will also recognise.

All have undergone some structural changes and the paint scheme has also been edited a little. Enjoy!

[MarkSheppard]

Oh, if it's not too much work, perhaps you could write a little manual to go with the mod; so that we know what is what, and why it was developed.

I mean, all of us when we play WinMBT, we know what a Leopard 1 and 2 are; along with M-48, M-60 and M-1; but we don't know that for your alt history units.
