Stealth Operator is on a mission to protect our protectors, and they proudly provide armor to first responders, law enforcement and military agencies. Phalanx Defense Systems provide you the same high quality armor that they trust to protect themselves.

Multi-Hit Tested

Each plate is tested to withstand multiple hits without being compromised.

We believe these devices should be worn to save lives, and we want to give our
customers the highest level of protection that makes sense for their situation.

All plates made by Stealth Operator, LLC are Stand Alone Plates that provide
all of the protection you are seeking at a reasonable price.


Priced With You In Mind

Cheap body armor is likely made of cheaper material, made outside of the United States or made in facilities that are not well equipped.

Some competitors’ best selling plates are ‘in conjunction’ plates, where purchasing means you will need to invest in additional soft panels or hard armor to reach the protection level you are trying to achieve. All plates made by Phalanx Defense Systems are Stand Alone Plates that provide all of the protection you are seeking at a reasonable price.

Unprecedented Warranty

Industry average warranty for hard armor plates is 5 years. Phalanx Defense Systems’ most popular plates (M2, M3, M7X) have a 7 year warranty, one of the longest warranties on the market. Our plates are more protected from the elements and daily wear-and-tear than our competitors with their special coating. We want you to make your investment in the best product and know that it will last you for years to come.
