I can't comment about the CRATOS as I have no firsthand knowledge of it, although like others have said its restriction centers around it's laser. However, in the NV/thermal industry a lot of products are made to fill certain specifications set forth by DOD, etc. and the development of said products is often partially or totally funded by the govt who then places limits on the mfg about who they can sell said product to once the initial contract is completed. Also as previously stated, even if all the development is totally funded by the company, sales outside of contract are restricted as a stipulation of the contract. Money talks and private sales of NV/thermal make up so little of the market share that no company is going to pass on a big contract just to sell a few units to us civs.
