Sure. Without going into specific customers, there are law enforcement agencies across North America, in Europe, and in Asia that use this sort of equipment. It's becoming increasingly prevalent.
The United States tends to be an early adopter of this type of technology. They have very strong budgets that go into Homeland Security programs. The federal government in the United States will provide grants from the federal level that will flow down to state and local law enforcement groups, specifically to equip those groups with this type of specialty equipment.
We've seen an increase in this type of equipment purchase overseas in places like China, India, Japan, and South Korea.
