It also wants to fully use tungsten alloy bombs, But it can't be used, But as a nuclear Power, There is a lot of depleted uranium as nuclear waste, so depleted uranium is selected as a substitute. As for tungsten alloy and depleted uranium, after putting aside the key additional condition of radioactive pollution, the pure question of who is better in armour-piercing performance is not directly related to this article, so it will not be described in detail).如果你能触摸我We now look at the heated IQOS cigarette bomb.
