An Amazing Display Of Weapons and Counter-Weaponry from the United States Military

There is nothing like looking at some American firepower to jumpstart your day. Most of these appear to be test runs conducted by the United States Army and not from combat. Enjoy!

Watch

In case some of you are wondering what the beautiful, fire-works-like, flares are from the helicopter and other aviation vehicles shown above- They’re infrared countermeasures used to redirect missiles using heat signatures.

More information brought to you by Wikipedia:

Most flares, like the MJU-27A/B flares, must be kept in an airtight storage compartment before deployment. These flares, known as pyrophoric flares, are made of special materials that ignite when they come in contact with the air. This is a safety and convenience factor, since attempting to ignite a flare inside the fuselage and then deploying it is risky. However pyrotechnic flares (such as the MJU-32) also exist, and offer their own safety benefit; requiring an external ignition method, an accidental leak or puncture in the storage compartment would not result in a catastrophic fire on board the aircraft as with a pyrophoric flare.

Deployment

Flares are most commonly gravity-fed from a dispenser inside the aircraft’s fuselage. These dispensers can be programmed by the pilot or ground crew to dispense flares in short intervals, one at a time, long intervals, or in clusters. Most currently used flares are of the pyrophoric variety, and thus the dispensers do not have to ignite and deploy the flare at the same time. With pyrotechnic flares, a lanyard automatically pulls off a friction cap covering the exposed end of the flare as it falls from the dispenser. A friction surface inside the cap rubs against the exposed end of the flare (similar to a match-head and striking surface) and ignites the flare.
