Depending on a person's weapons interest, he can pursue a job that specifically addresses the technical designs and implementations of warfare tools and machines. For example, mechanical engineers "research, design, develop, manufacture and test tools, engines, machines and other mechanical devices," according to the U.S. Bureau of Labor Statistics' Occupational Outlook Handbook. Aerospace engineers design and test aircraft and missiles. Nuclear engineers work with tools and resources that use radioactive materials. Marine engineers and naval architects design and construct ships, boats, aircraft and tankers.
Take extra high school classes in mathematics and science, and score as high as you can. "Admissions requirements for undergraduate engineering schools include a solid background in mathematics (algebra, geometry, trigonometry and calculus) and science (biology, chemistry and physics)," advises the Occupational Outlook Handbook.
Graduate from a college accredited by the Accreditation Board for Engineering and Technology with a four-year degree in engineering. "Engineers typically enter the occupation with a bachelor's degree in an engineering speciality," according to the Bureau of Labor Statistics,"but some basic research positions may require a graduate degree."
Graduate from an accredited graduate school in engineering or business administration if you plan to teach in the future.
Apply for and obtain an official license. If you are going to be an engineer who offers your services directly to the public, then you must become licensed, writes the Bureau of Labor Statistics on its website. Requirements for a license usually are a degree from a program approved by the Accreditation Board of Engineering and Technology, four years of work in the field and passing your state's board exam.
