“…In particular, mobility of the lower limbs is crucial to individual performance and safety of soldiers during military operations because walking and running are quintessential ways of locomotion in a combat zone particularly for infantry soldiers (Man, Swan, & Rahmatalla, 2006). A typical repetitive activity of soldiers is walking while wearing a heavy ballistic vest with an attached personal load.…”

This study investigated the impact of body armor weight and load magnitude and distribution on the lower extremities during walking. Range of motion (ROM) was assessed while seven healthy, male, right-handed, military university students walked while wearing seven different garments of varying weights (0.06 kg, 9 kg, 18 kg, and 27 kg) and load distributions. Decreased pelvic rotation found with an increase in weight implies decreased mobility by restricting the leg's swing to propel the body forward. Increased ROM for pelvic tilt found with increased weight results from increased forward inclination suggesting an increased possibility for fatigue and musculoskeletal pain in the lower back. This study substantiated that a balanced weight distribution can minimize risk of chronic lumbar pain by reducing forward lean of the trunk or pelvic tilt; a balanced weight distribution around the torso at a level of 27 kg showed less change in ROM for pelvic tilt than an unbalanced weight distribution.

“…Mobility of the lower extremities is critically important to an individual soldier's performance and safety in the combat zone since crawling, walking, and running are basic movements necessary for military operations in combat zones (Man, Swan, & Rahmatalla, 2006). Therefore, restricted lower body movement can have negative impacts on military operations and soldier safety.…”

This study investigates the effect of wearing body armor while walking on lower body mobility using a motion capture system. Seven male participants participated in a walking test while markers were attached to anatomical points on their joints under two garment conditions. The treatment garment was an 18-lb ballistic outer tactical vest with inserted ceramic front and back plates and the control garment was a pair of sports shorts. The walking test was repeated 5 times per subject. Wearing the outer tactical vest significantly increased stance phase, double support, knee flexion, foot plantar flexion at the ankle, and anterior pelvic tilt. Wearing the outer tactical vest significantly decreased swing phase, posterior pelvic tilt, and pelvic rotation. The increase in knee flexion and plantar flexion while wearing the outer tactical vest may accelerate fatigue and increase energy expenditure, which can negatively affect soldiers' performance and safety by increasing injury risk.

“…Each of these systems has evolved over time to provide the best balance of protection with encumberment for the application. Through modelling of human motion such as the work of Man [136], inspiration could be drawn from all of these for future protective systems for the modern battlefield.…”

The development of armour is as old as the dawn of civilization. Early man looked to natural structures to harvest or replicate for protection, leaning on millennia of evolutionary developments in natural protection. Since the advent of more modern weaponry, Armor development has seemingly been driven more by materials research than bio-inspiration. However, parallels can still be drawn between modern bullet-protective armours and natural defensive structures. Soft armour for handgun and fragmentation threats can be likened to mammalian skin, and similarly, hard armour can be compared with exoskeletons and turtle shells. Via bio-inspiration, it may be possible to develop structures previously un-researched for ballistic protection. This review will cover current modern ballistic protective structures focusing on energy dissipation and absorption methods, and their natural analogues. As all armour is a compromise between weight, flexibility and protection, the imbricated structure of scaled skin will be presented as a better balance between these factors. TOPICAL REVIEW RECEIVED
