How Does Every U.S. Military Branch Solve Crimes?

The U.S. government has a set of federal law enforcement agencies that conduct investigations on offenses dealing with all of its military branches. These agencies are the Naval Criminal Investigative Service (NCIS), Army Criminal Investigation Division (Army CID), Air Force Office of Special Investigations (AFOSI), Coast Guard Investigative Service (CGIS), and the smaller Marine Corps Criminal Investigation Division (Marine CID).

These military law enforcement agencies fit perfectly in between the civilian and military law enforcement worlds to enforce and investigate major crimes and offenses with any connection to the Department of Defense. These agencies all have special agents with arresting powers that are either civilian or active duty military.

But why does the United States have these military law enforcement agencies? What exactly do they do? Why do we even need them? And most importantly, what separates them from the rest of the numerous law enforcement agencies throughout the United States? If you’re interested in learning more about these military law enforcement agencies, watch this video!

Who here knew about all of these military law enforcement agencies before this video?

[Rasdawg]

I seen NCIS bust in and arrest a guy at the barracks once. It was the funniest $#^t ever.

[azcountry]

"Do What Must Be Done” Brothers. Retired Army CID. Glad to hear they are going 1811.

[mrmacguffn]

My dad was a JAG and Judge for the Air Force for most of his career, so i definitely heard about OSI

[darylcheshire]

In Melbourne, Australia during WW2 there was a series of murders called “The Brownout murders”, the guy was a US serviceman call Eddie, he was sentanced to be hanged in Melbourne’s Pentridge Prison. It was approved by Gen. Douglas MacArthur, but it was later found that ultimately was approved by President Roosevelt.
I read a bunch of US soldiers (MPs?) visited Pentridge and said “stand aside bud, we need to use your gallows”.

14:11 the coast guard is actually more unique in that it doesn't just fall under DHS, it is mobile. If congress were to declare war, or if the president issued an executive order, the coast guard would move from DHS to a component of the Department of the Navy, like the Marines.
As the Coast Guard is a federal law enforcement agency in its own right, CGIS is also unique in that it is the only federal law enforcement agency tasked with policing another federal law enforcement agency.

You guys should definitely do a video explaining the differences about every military law enforcement/security SWAT teams in every branch such as the Marine Corp (SRT, FAST, RTTs), Navy (SRF, VBSS, Riverine's), Air Force (ESTs, TRF, DAGRE, RAVENs), Army SRTs, and Coast Guard (MSRT, MSSTs, TACLET)

Many years ago, while serving at CRC 2ID, there was a Korean national lady who was murdered just outside post in a bar. The Lucky Club. They knew it was a service member but not who. CID had every battalion do a stripped down inspection of all soldiers of every rank, male and female.

All soldiers who were found to have any marks of any kind were set aside after having gotten redressed. They were then marched to CID and questioned, shown pictures of the crime scene, finger printed, etc.

I don't think it included Camp Casey but they eventually found the guy within like a month if i remember right.

That was a whole different experience.

I proudly served as both an AFOSI agent and a CID agent.

[josephdvo]

I saw my old boss running the polygraph exam for OSI, texted him to let him know he’s famous (or maybe infamous depending upon who you ask).

[taylorpearce]

Air Force osi has alot more specialties in line with ncis, also the fbi ncis and osi are the only three agencies that do both Crim and CI. OSI has a larger deployed mission than the other branches. OSI also does citp and has an 8 week follow on.

[clifbradley]

My aunt was OIS in the late 80's. She had the unique distinction to be the only agent to kill someone with the .357 Magnum and to do it the day before they phased the guns out. She shot a civilian in the Philippines. If you want, I'll share the story. Just let me know. It involves beheading, homemade guns, and giant sugar barrels.

Every service component’s Military Police organization will conduct criminal investigations up to a certain threshold, above which their special investigative organizations will assume responsibility. This threshold will vary depending on service guidance, local capabilities and workload, personalities, and so forth. For example, in my first Air Force assignment, our local OSI detachment would not take any drug cases if they involved less than an ounce of marijuana. Because they had this discretion, they would also defer on a variety of criminal cases if there was no suspect, little evidence, or other conditions that may negatively impact the clearance (solve) rate. Take from that what you will. All these special investigation organizations are separate from the local military police and installation chain of command to maintain independence, since they also investigate fraud, official misconduct, procurement irregularities and so forth.

Missing DCIS and Army Counterintelligence

[Scimetar]

An excellent example of one of the agencies covered in this video is the fictional case of Supervisory Special Agent Leroy Jethro Gibbs, from the CBS show NCIS. The show is about a team of fictional NCIS agents that investigate homicide cases involving either the US Marine Corps. or the US Navy based out of the Navy base in Norfolk, Virginia. In the case of Agent Gibbs, his backstory says that he was medically discharged due to psychological issues stemming from the murders of his wife and daughter during Desert Storm, and is now the lead agent on their team. Another fictional and related case from the same show is Agent Samuel Hanna, a retired US Navy SEAL. A third, more removed example, once more from the same series, is Agent Timothy Macgee, the son of a four-star admiral who ended up rebelling against his father's pressure to join the navy, joining NCIS to still serve the navy while doing police work on their behalf.

it gets very complex overseas as well because jurisdiction can be a convoluted maze depending on the circumstances of the crime and the agreements that are in place with the local government.

i think they have very limited ability to arrest civilians outside the united states or military bases.

[jed-henrywitkowski]

When my brother was in the Corps, the MPs brought in a Marine to the bring. He had been AWOL since Nam.

[drummingninja]

Army CI falls under this too. They dont focus on major crimes. Army CID does. But ACI are special agents as well. And have similar jurisdiction to CID.

[gatorcroc]

05:33 I do wanna point out and or clarify that not all NCIS agents are civilians. There are many Navy Reserve members that are NCIS agents and drill at your local NRC / NOSC. So yes you can be an NCIS agent and a Navy Sailor.
