Approved sources include Lockheed Martin Corporation, Oshkosh Defense LLC, and 2IS Inc., and respondents must provide the manufacturer’s location and point of contact. No budget information is specified, and no performance location is mentioned. This is not a request for proposal, and no contract award will result from this notice. Responses should be submitted to Cassandra Blagmon at the provided email or phone number.
