&gt;Because, as the people of Kuwait discovered after first Gulf War, depleted uranium leaves a potentially deadly dust behind after it burns. It sounds bizarre but, in the world of warfare, tungsten is the eco-friendly alternative.<p>i knew it is bad, just googled and according to some sources it is really bad, especially when it comes to birth defects :

Unfortunately, DU is still better for armor penetration : <a href="https:&#x2F;&#x2F;www.theguardian.com&#x2F;world&#x2F;2000&#x2F;may&#x2F;18&#x2F;armstrade.kosovo" rel="nofollow">https:&#x2F;&#x2F;www.theguardian.com&#x2F;world&#x2F;2000&#x2F;may&#x2F;18&#x2F;armstrade.koso...</a><p>&quot;Armour penetration is increased by concentrating the force of a shell into as small an area as possible, so the projectiles tend to look like giant darts. [ ... ] The other metal used for anti-tank rounds is tungsten, which is also very hard and dense. When a tungsten rod strikes armour, it deforms and mushrooms, making it progressively blunter. Uranium is &quot;pyrophoric&quot;: at the point of impact it burns away into vapour, so the projectile stays sharp. &quot;
