The theme of this article is the care of casualties in the field from the perspective of the increasing digitisation of the combat zone. The authors describe the medical data-handling project CORTIM, for which the Armed Forces Medical Service (SSA) was awarded the prize for bold innovation in 2006. Starting from an updating of knowledge of current situations, CORTIM has created a Theatre Medical Control System (RMT). The project and RMT are being followed closely by the SSA, DGA (the French armaments agency) and Army Staff.
