helicopters in the indian navy.

helicopters are loaded in the indian navy, of all sorts and all colors. as far as the defense is concerned ... umm i don't know. all day you will see them flying all over the place. 
   i never had them as pets, tying a tread on their rears and carrying them where ever the go,  but when i took a closer look i really didn't understand any pattern they randomly fly and collide into the wall. 
at first i was excited to find them and started collecting them, but soon i figured they are fallen dead all over the place.
