Those structures requiring essential medical coverage by a plate were demonstrated to be the heart, great vessels, liver and spleen. For the 50th centile male anthropometric model used in this study, the front and rear plates from the Enhanced Combat Body Armour system only provide limited coverage, but do fulfil their original requirement. The plates from the current Mark 4a OSPREY system cover all of the structures identified in this study as requiring coverage except for the abdominal sections of the aorta and inferior vena cava. Further work on sizing of plates is recommended due to its potential to optimise essential medical coverage.

IntroductionOSPREY personal armour has been issued to UK forces since 2005. From 2015, the VIRTUS personal armour and load carriage system have been progressively replacing OSPREY. In 2016, the ban on women in ground close combat roles throughout the UK’s Armed Forces was lifted. In anticipation of this, work has been ongoing to prepare future ballistic protection programmes for a potential increase in the number of female users.MethodA human factors questionnaire was provided to 150 female users of OSPREY body armour to complete while on combat operations in Afghanistan. The questionnaire asked the users to rate the comfort of their OSPREY body armour along with their ability to carry out basic tasks. Other background data such as size of body armour worn and bra size were also collected for the analysis.ResultsThe female participants reported various types of discomfort when wearing their OSPREY body armour, with 135 instances of discomfort experienced in the hip region, for example. Challenges were reported in the ability to carry out basic movements, with the tasks rated on a Likert scale as difficult or very difficult by between 29% and 59% of participants. In addition, a restriction in ability to access personal equipment worn on the person (including pouches, trouser pockets) was commented on by 39% of participants.ConclusionsFemale users reported challenges relating to the fit and function of OSPREY body armour. The VIRTUS body armour system for UK Armed Forces Personnel has already addressed many of the reported issues with OSPREY. Further optimisation for VIRTUS with regard to female users is planned and includes sizing of ballistic hard plates.
