Apart from their additional weight vests block natural ventilation,
preventing sweat heat dissipation. Physiological tests have demonstrated
that body and surface temperature of soldiers wearing bulletproof
vests can rise by up to 2C degrees (4F) after one hour continuous
physical workout, compared to those not wearing vests. Since sweat
is gathered between the shirt and vest, air becomes saturated
with humidity and the body's natural cooling process renders ineffective,
resulting in increased heartbeat and body temperature, to extreme
levels effecting physical and mental capabilities.
The introduction of "breathing" clothing apparatus,
such as athletic garments,
active air circulation or
micro-cooling, as well as redesigned
protective vests, introducing larger gaps
between the uniform and shield could reduce such adverse effects
improving the soldier's sustained physical abilities.
Improving mobility of individual soldiers can be achieved by
providing lighter, improved fitting and more comfortable equipment,
and optimizing to physiological conditions under which they fight.
Infantrymen usually go to war carrying loads of up to 50 kg, including
personal and mission-specific equipment. Infantry combat suits
are designed to reduce this load below 25kg. Further mobility
improvements include providing pads to protect neck, knees, elbows
and shoulders. Such pads offer mechanical or ballistic protection
and assist the soldier in maintaining positions for extended durations.
Another mobility improvement can be achieved by offloading some
supplies to onto a small load carrier, be it exoskeletons,
an ATV or small and maneuverable robotic
"mule" which can closely follows the troops.
