JAG, or the Judge Advocate General’s Corps, is the largest and oldest law firm in the United States. Founded by George Washington in 1775, JAG was abolished in 1802, but made a comeback nearly fifty years later and has been around ever since.

After creating the first JAG school in 1942 and growing tremendously in size, the JAG corps has become an essential part of the military. By the 1950’s, JAG managed to overhaul the entire military law system and create the Soldier’s Bill of Rights in order to ensure fair and humane treatment for all enlisted individuals.

It’s been involved in everything from prosecuting President Lincoln’s killer to convicting Major Nidal Malik Hasan in the Fort Hood shooting that took the lives of 13 service members in 2009.

From the Revolutionary War to Afghanistan and Iraq, JAG professionals have served wherever they’re needed since JAG was founded.

If you become an attorney, you’ll be responsible for prosecuting criminal cases and giving legal advice to enlisted individuals and their loved ones. Paralegal specialists, on the other hand, tend to work more on the administrative end of things.

For instance, while paralegals aren’t in charge of prosecution, they often do much of the paperwork involved with military court cases.

They also help with family law matters. Both paralegals and attorneys are important, but since attorneys have more responsibility, you can only work as one if you’re an officer.

If you’d like to be a paralegal, you only have to be enlisted in the military.
