The questions are as follows:
What are the differences between a rocket, a missile, and a shell?
What are the pros and cons of a UAV (unmanned aerial vehicle - a military one)?
What is Acetone, and what is it used for in military forces?
These are for some contest I'm entering, problem is I can't seem to find any information about it I'd be over the moon if anyone could give a hand here.. Thanks.
