The United States Marine Corps is back in the Law & Order: SVU building, baby!
Stabler served in Operation Desert Storm, and was a hand to hand combat specialist while in the military, and his service was an important part of his character.
What was also an important part of Stabler’s look was this tattoo of the official Marine emblem on his forearm, so even if Christopher Meloni hadn’t captioned this picture “first day of school,” I doubt that any of his fans would have missed the obvious fact that this bit of body art means that he’s getting back into character and on set.
