have evolved, their original 256 MB RAMs and 20 GB drives having been superseded by 512 MB RAMs and 40 GB drives. The contractor for supply of Portable User Data Terminal (PUDTs), based on a 266 MHz Intel StrongARM processor, was L-3 Communications. The PUDT is now obsolete and is not used. Extensive problems with the software running on low powered computers led to the procurement of a number of enhanced computers, the Lightweight Tablet (LTDT) manufactured by Blazepoint and Lightweight Manpack (LMDT) produced by L-3. In addition to processing limitations, the larger UDTs have significant ergonomic issues and were supplemented with a buy of General Dynamics Itronix computers modified in the UK by Blazepoint to support systems managers and communication planners. Responsibility for the supply of Bowman audio ancillaries, including the stereo staff-user headset, noise-cancelling general-purpose handset, and loudspeaker unit, was vested in Selex ES, which also provided the lightweight headset, respirator adapter, and remote pressel switch associated with the PRR. Racal (now Thales Group) provided antennas for the Bowman contract. These include HF Wire/Vehicle, VHF Vehicle/Elevated, VHF Ground Spike, 5.4 metre GRP Mast and UHF Vehicle/Elevated Antennas. Additional antennas supplied as part of the Bowman contract are the man-pack antennas, which are supplied together with the matching unit by MGS Precision, based in Stone, Staffordshire. BISAs Bowman also consists of a number of specifically designed Battlefield Information System Applications running over the Bowman infrastructure. The UDTs (User Data Terminals) are currently limited to supporting a maximum of two BISAs simultaneously, due to the performance limitations of the UDTs. ComBAT, produced by GDC4S in the US, the main Command and Control (C2) tool for Bowman has faced early criticism relating to performance, ease of use and interface design. A significant portion of these problems have been addressed in later version of ComBAT. BISAs include - ComBAT (C2 & situational awareness (SA), GBAD (Ground Based Air Defence) Command & Control, Makefast (Engineering) and FC (Fire Control). Controversy When Bowman was first introduced into service, the system was said to contain many faults to the extent that troops dubbed Bowman "Better Off With Map And Nokia". The programme came under scrutiny following a National Audit Office accountability hearing for the government's procurement policy and was generally considered to be a success considering the complexity and changing needs of the UK Armed Forces.
