Bomb suit (NCIS S08E03)

TV show
NCIS Season 8 Episode 3 titled "Short Fuse"

Storyline
Marine Sgt. Heather Dempsey (a member of the bomb squad) shoots and kills an intruder in her home. Tony is apparently being prepped to be the new face on the NCIS recruitment brochure, but then the team is called in to investigate the shooting. It seems like a simple home invasion robbery at first, and Heather claims she was alone in the house at the time. Tony discovers evidence that suggests a man was there at the same time. Heather's 911 call also includes a man talking in the background. Abby gets the intruder's gun to try to trace it, but the serial numbers have been filed off. Ducky notices that someone removed the intruder's fingerprints, making it next to impossible to figure out his identity.

During the investigation, a bomb threat is called in from the naval shipyard and Heather is called in to help. Ducky figures out that the man had a liver transplant, so Abby uses that information to try and ID the intruder. Meanwhile McGee is tracing all cell phone activity in the vicinity of Heather's house, and there's a single number he can't trace the owner of, because it belongs to the FBI. The team contacts Fornell.

The number is owned by Gary Tolin, the Executive Assistant Director of Criminal Investigations. Fornell calls Gary into NCIS at the same time as Heather's interrogation, but Gary isn't very cooperative. Heather admits that she and Gary met at a function and they headed to her house afterwards, but Tony suspects that they're not telling the entire story. Meanwhile Abby IDs the intruder as Glover Reese, a contract hitman. But who was he sent to kill, Gary or Heather?

Fornell and Gibbs figure out that Gary has been working on a lot of high profile cases, including one where he negotiated a plea bargain for a drug dealer named Gene Abbott. Abbott was involved in a shootout where Heather's brother was caught in the crossfire and ended up paralyzed from the chest down. As part of the plea agreement, Abbott gave up the identities of his associates in exchange for avoiding jail time. Heather used Gary to find out where Abbott was living now.

The team head to Abbott's farm, where they find him strapped in a chair with a motion-sensitive bomb in his lap. He'd already been there for a couple of days, and Abbott confesses that he was the one who'd sent the hit man after Heather. Heather admits that the bomb was a fake, and that she just wanted Abbott to experience what her brother has to go through every day, not being able to move and not being able to do anything for himself.

Tony is excited to see the new NCIS brochure but is disappointed when Gibbs turns out to be the cover instead.

What we learn?
We'll learn about that fancy suit worn by Dempsey. It's "bomb suit".


What is it?
A bombsuit or Blast Suit is a heavy suit of personal armor designed to withstand the force released from a bomb. It is also sometimes referred to as a Demon suit due to the number of people who are killed in the suit.

In contrast to ballistic armors, which primarily focus on protecting the torso and head, a bomb suit must protect all parts of the body equally, since a bomb's force always impacts the entire body.

Being a suit designed to withstand explosive force, it is very heavy, bulky and difficult to maneuver in. These drawbacks make it unsuitable for combat situations. However, they are often used by explosives experts while attempting bomb disposal.

Materials?
Bomb suits are made of Kevlar or some other aramid-based product. Aramid (the generic name for Kevlar) consists of synthetic fibers woven from polymers -- large molecules made from strands of smaller molecules called monomers. Aramid's outstanding strength-to-weight ratio makes it an ideal fabric for bulletproof and blast-resistant clothing.

Additional foam or other padding may be incorporated throughout the bomb suit. This offers protection to the wearer not only from flying debris, but also from the force of impact that occurs when the wearer of the suit is thrown to the ground.

The garment has internal pockets consisting of webbing and Velcro inside which ballistic plates can be inserted. These plates are made of steel, aramid or coated ceramic. They're designed to protect the wearer from fragmentation.

WTF?! It's bare handed!
Many suits are designed without protection for the wearer's hands. This is calculated rather than careless: The technician will likely need his or her hands free to defuse a bomb.

Watch it in real life!
