My question is: how has war stayed the same even technology has changed so much?  

I believe the war now is not so different from a long time ago.

I just love the history of the war.

the pitcher on the top is a 2k16 tank.  the picture on the bottom is a knight on a horse the knight on horse is the tank of its time.

THE PICTURE ON THE TOP IS A KNIGHT FROM A LONG TIME AGO AND THEY FOTE WITH WHAT THEY ARE GIVEN AND SO DO THE ONES ON THE BOTTOM..

PICTURE ON THE TOP ARE PEOPLE WITH LONG BOWS AND THE PICTURE ON THE BOTTOM IS A ANTI-TANK LAUNCHER the people with long bows are ANTI-TANK of their time. 

this is AR 15 armor penetrating ammo. time to go to the video.
