Railway guns

    During WW1 and WW2 the concept of military might was to create bigger and more powerfull guns, and so the tanks and artillery was invented. And as if that wasn't enough even larger guns were created for naval battle ships. 

But the race wasn't ended there, they even created guns so large that can't even be transported by normal means, they created      THE RAILWAY GUNS.

    These guns were so massive that they could fire 800 mm (31.5 inch) diameter ammo. Which was enough to penetrate and destroy any bunker of that time. 

Many of such massive behemoths were created by many warring nations, but the largest of them all were DORA and GUSTAV guns created by Germans.

Gustav round

    The thing was these guns were so massive, slow and required man power that they were an incredible waste of resources. Similar and even stronger ordinance could be transported via a bomber, rocket or a missile. And they were even limited to railway transport, making them an easy target for aircrafts.

 Gustav firing

   The DORA never saw action, only Gustav did, and it successfully destroyed a British ammo dump.

Explosive rat

      Perhaps one of the most weirdest weapons used in WW2 is the explosive rat. 

       This rat bomb was developed by British SOE during WW2 as a booby trap. The idea it self was very simple, a rat was skinned, its internal organs were replaced by a plastic explosive, with a time fuse which will ignite the P.E when rat was exposed to fire, then the rats were to be distributed near German boiler rooms, on their coal dumps. 

       When some one would see a dead rat they would think it died by coal poisoning, and they would immediately throw them in the furnace, the rat would then explode resulting a boiler explosion, and sabotage German operations. 

    How ever this ingenious booby trap never actually saw its real use. The first shipment of explosive rats was intercepted by Germans. 

      How ever the discovery of this weapon did a really effected enemy troop morale, and they were practically ordered to kill and dispose of any rat they see on sight, the resources Germans wasted on disposing of rats caused more damage then their intended use, and therefore the operation was considered a success.
