text: invention..? to upgrade some thing , or to invent. do you need an engineers degree? i have an idea of an invention, for the army. i have a few sketches of it. since i don't know much about materials , or have the equipment , i can't make it. so how do i go about , doing so? does the army , take offers. hypothetically. if i actually made this product and  i wanted to sell my product to the government/army , can i? all of the army/marines equipment , such as trucks / weapons and i believe tanks/planes , aren't made by the government. i'f i'm correct.   can i make the product my self? if so how? or do i need to contact a manufacturer and , just sell them the idea? no, you don't need a degree but you must be aware of the tools and techniques needed to fabricate things. many of the great inventors did not even have a formal education but they had hands on experience in makng things.
