Kerry getting elected would be like us joining the EU and letting france dictate what we should do.

Fuller sees Grant's Vicksburg campaign as brilliant. Following Fuller's argument carefully and in the light of my other reading I came to agree with General Fuller.

Fuller on Cold Harbor is very interesting.

The Donalson - Henry campaign is a strategic gem. The repair of the Chattanooga situation was masterly. My own opinion, of course.

Grant himself was very proud of Chattanooga, as well as scandalized by Rosecrans. (From his memoirs.)

Diameter of the projectile doesn't have all that much to do with armor penetration. It is more a matter of force per unit area integrated over the time of penetration, I think.

Extremely good links, non-technical, on the subject:

There is a wealth of good material at the above sites. Something more modern:

You add a lot to the Foxhole. You bring the true spirit and no lies. Duty, Honor, Country.

The second sentence of the first paragraph is totally wrong.

More like, the penetrator has to apply enough force to the armor that the armor flows away from the penetrator like a finger pushes into room temperature butter, or like the finger being pushed through a graham cracker. The second is called "brittle fracture".

Thanks for the clarification.

Looks like I've got some reading to do this evening. Thanks Iris7. You're one of the many reasons I love it here. :-)

The second sentence of the first paragraph is totally wrong.

I actually knew that . . . before I didn't know it. ;^)

Seriously, thanks for your efforts and expertise. I checked out some of hyperlinks . . . very informative.

LOL!

Thanks for fixing the pic. Thought I'd checked the code pretty carefully but musat have missed the obvious.

[SAMWolf]

Thanks Iris7.

Some of the stuff I've read about armor and shell penetration is way above my understanding, nice to see it put in plainer terms.

[SAMWolf]

Thought I'd checked the code pretty carefully but musat have missed the obvious.

It took me three tries to get it to work. It wasn't all that obvious. ;-)
