The Defense Health Agency’s JOMIS PMO is conducting market research via an RFI for operations and sustainment of the BATDOK family of systems, with the anticipated period of performance beginning 1 October 2027. The BATDOK FoS includes BATDOK-J, an Android/iOS point-of-injury casualty documentation app; BATDOK Link, a Windows plug-in for data transfer into MHS GENESIS Theater or OMDS; and BAT-TAK, an ATAK Android plug-in. The RFI seeks potential sources, including small businesses, with demonstrated DoW experience developing, sustaining, and integrating tactical mobile applications on Android and iOS plus associated ATAK and Windows plug-ins. It also seeks industry input on technical approaches, best practices, and innovations for achieving draft PWS outcomes and to inform acquisition strategy, including contract vehicle, contract type, small-business set-aside determination, and performance measures. This is solely an information/planning RFI, not an RFP/RFQ, and does not commit the Government to issue a solicitation or award a contract.
