Description
A tank from the 5th Brigade the Guards Grenadiers of Horse, who operate a little further north of the capital area in Anemos Major in the Duchy of Fierei where the land is a lot more level with far fewer trees than the forested regions that lay to the south.This is a First Production Standard vehicle - essentially, Block I.
Please leave comments, it's nice to know what people are thinking.

It's not, no - it's based off certain elements of real tanks, though (the very low turret profile stems from a Wegmann proposal for a future Leopard 2 turret, the hyperbar engine and compressed air gun extraction system are lifted from the Leclerc, etc).
Fundamentally I'm not actually all that happy with this, and look forward to drawing up a new MBT reasonably soon!

hahahah, kind thanks! actually not all that happy with it, hope to replace it soon

cool! I love all of your tanks

Now I'm not an expert, but wouldn't a flat turret flat like that mean your tank would have absolutely zero gun depression or elevation?
π: 0 β©: 1
Nah - at least, not on this vehicle. Normal gun turrets have a gun depression that's restricted by the turret roof, true, but in this case there's actually a flap along the top of the turret that essentially moves that part of the roof alongside the gun. Cue somewhat more complex mechanical construction (and the need for more powerful electrical motors driving the gun depression), but also the ability to have a fairly significant depressive range alongside a low profile turret.
Wegmann (of KMW fame) came up with a concept along those lines for a Europowerpack driven Leopard 2 back in the '90s, if you can dig that up.

Ah darn. I have a massive bulging monster of a turret on the tank I'm making right now. Out of curiousity, what's with the little tower thing just in front of the remote weapons station?
π: 0 β©: 1
Well, I mean, the vast majority of conventional turrets don't have Wegmann flaps.
That's the commander's independent sight.

What did you use for this? I really need to make these sorts of drawings for my own designs.
π: 0 β©: 1
No way! That is awesome!
π: 0 β©: 1
Damn, that is the best looking tank I have ever seen.
I guess I'llnever make a tank...
But truly awesome work!

*I guess I'll make a tank again- That is what I meant to say.

Do you do commissions?Β
Btw great work!Β
π: 0 β©: 1
No commissions, I'm afraid. I only really do this for fun and NS, and pretty much exclusively when I have time to burn
Thanks very much for the kind words!

You're welcome!
Oh, yeah! And by the way, I decided to watch you.
π: 0 β©: 1
A-ha! Well, let me return the favour
π: 0 β©: 1
Not 100% sure just yet, hashing out the complicated technical bits right now.
What I *do* know - 128mm L/55 Solid Propellant Smoothbore, 74t or so with a 10 cylinder opposing piston VG diesel hyperbar to keep it trundling along, with a hydractive suspension. I *want* the transmission to be hydromechanical, but I need to go over the charts again to see if I can make something that can adequately handle the 70~t weight range while still feeding enough power to the tracks.

This is fantastic, as always. I look forward to the writeup.

Thank you very much.
My apologies for not working on that thread - it just got into my mind that I needed to just sit down and finish this off. To be entirely honest, I actually wanted to try using this in a thread at the end of it all

Your welcome for the reminder,HMF would be most inclined to buy the HT9A8.

Not sure what the export situation with this will be, I'll figure it out
π: 0 β©: 1
I would propose a package that consists of some Illusions, Army startup package and some ships.
π: 0 β©: 1
The ships have always been a bit iffy, since short of the Astela they're just me offering storefront space for another nation
π: 0 β©: 1
Ok then, perhaps Anemonian ships would be a good idea?
π: 0 β©: 1
If only I had the time for all that.
π: 0 β©: 1
I mean, it wouldn't be impossible - I already have a half-complete DDGH in my linearting folder, it's just that the other half is harder than it looks

Have you gone to Shipbucket ?
π: 0 β©: 1
There's nothing for me at Shipbucket - all my parts would be domestic anyway, so there's no point in going to use theirs.
π: 0 β©: 1
Ok then, try perhaps.

I have a translation job on my hands right now, and a two week getaway holiday with the important person in my life in a week's time 
π: 0 β©: 1
What sort of translation? And well have a good time.
And best of luck.
