Evaluation of a method for developing scaled plate sizes to maximise accommodation rate of high velocity ballistic protection for the Australian Defence Force.

Project Details


The Australian Defence Force (ADF) adopted a single size of Hard Ballistic Plate (HBP), the CIB 24/25, when the Tiered Body Armour System (TBAS) was rolled out in 2011. Consequently, irrespective of carrier size, the current front and rear HBP plates, (CIB 28/29) have the same dimensions (246 mm (w) * 296 mm (h)) across all ADF body armour systems. This single size approach does not take into account the variability of body shapes of military personnel. For example, soldiers with; large torso soldiers may not be adequately protected, and soldiers with smaller torso, soldiers (particularly females), are reporting TBAS interfering with mobility and comfort. Consequently it is estimated that current body armour HBP sizing accommodates only 12% of ADF Army males and 5% of ADF Army females.

Recently, Defence Science and Technology Group (DST) has used Coverage and Ergonomic Fit assumptions to identify a suite of 5 HBP sizes with an estimated total accommodation rate of 75% of ADF Army males and 64% of ADF Army females. Five plate sizes have been selected because 5 five sizes gives a moderately high accommodation rate for a feasible number of plates. This research project will therefore evaluate the suite of five plates against current issue ADF body armour.

In 2019 UC completed a research agreement with DST investigating the fit of in-service body armour systems on female soldiers. During that research project the primary investigator (CEC) developed domain knowledge, including that pertaining to the fit of the Solder Combat Ensemble for female soldiers. As the current research project builds on this prior work, Dr Coltman is being engaged to work with DST on this research project.
