The nature of the threat from Improvised Explosive Devices (IED) has changed the pattern and probability of injury for both mounted and dismounted personnel. The aim of the Horizon 0 Phase 1 and Phase 1a trials was to investigate the impact of various soft armour options on soldier mobility. The trials considered soldier task performance as well as soldier acceptance and comfort. The soft armour options varied in stiffness/flexibility, weight, bulk, and protection levels. Phase 1 was a five-day trial with twenty reserve soldiers and Phase 1a was a two day trial with eleven reserve soldiers. Participants undertook a battery of human factors tests while wearing test conditions in a repeated measures design. Fit, Range of Motion (ROM), discrete mobility, and compatibility test stands were conducted followed by dynamic assessments of mobility and agility. Data collection included questionnaires, focus groups, compatibility scores, performance measures, and Human Factors (HF) observer assessments. Test conditions used the Modular Tactical Body Armour System (MTBAS) armour carrier design, with modular add-on groin, neck, throat, and brassard protection. In general all conditions were in the acceptable range (greater than 4), with the exception of condition A (10 plies KM2 600 + 9 plies FR10 with 1.9 kg plates) from Phase 1a and condition Ninitial (2.1 kg/m2 KM2 400 (N1), 5.4 kg/m2 Spectra Shield SA-3118 (N3) with 1.4 kg plates) in Phase 1. It appears that bulk is a more
