Cougar was a trademark of Racal in the UK, used for a series of high-end portable, stationary and mobile radio sets, that were used by law enforcement services, security and intelligence agencies and the military. Many of the radios were equipped with strong voice encryption. The radios were used for covert operations, surveillance, observations, Special Forces Operations (SF), etc.

In 2000, Racal was taken over by Thomson-CSF, a French multi-national company with a strong presence in many countries. Shortly after the acquisition, Thomson changed its name to Thales. Thales has continued parts of the Cougar range (e.g. the PRM-5120 covert radio), under the name Cougar 2000, using the above logo as part of the new trademark shown below.

Under Thales, the Cougar product line was succeeded by the advanced Panter EDR VHF Tactical Communications System [1], which included one of the world's first Video-Over-Radio (VOR) surveillance systems — RAICATS — that had been developed at Racal in Bracknell (UK) in 1996.
