Whenever entering into unfamiliar territory it is a good idea to have a guide. When you are an unwelcome visitor in the land, it is a good idea to be your own guide. Since the United States Marines are not always a welcome visitor, it is a good idea to make sure that it is possible to survey the landscape which operations will take place and make sure that as much as possible is understood before any personnel enter the area.
What You Will Do
You will access different systems to provide you with the information you will need to help with mission planning. You will provide updates to existing maps based on changes in topography, water locations and much more. You will compare the information you gathered with the specific weapons systems which will be used in the area to make sure that there are going to be proper locations in which they can be used.
Get the Training
Assuming you meet the requirements set forth for the job like having a score of 100 or higher on your EL, eligibility for Top Secret security clearance and proficiency in certain high school mathematics courses, you will go through further training. You will go through the Basic Geographic Intelligence Course at Defense Mapping School in Ft. Belvoir, VA. You will learn everything you will need to know to properly help to provide the troops with the most accurate information before entering any situation.
