Military heavy vehicle drivers experience low-frequency vibrations that are associated with fatigue, drowsiness, and other adverse health effects. The existing research papers focus on performing different types of analysis, but few use advance signal processing tools based on recurrence plot representation; therefore, the main goal of this paper is to assess the whole-body vibration (WBV) and hand-arm vibration (HAV) exposure of a driver, comparing armoured personnel carriers and cargo destined vehicles. For this purpose, the power of a signal distributed over its frequency was analysed using power spectral density (PSD) and diagonal line quantification (DLQ) analysis. According to the results, in the case of the cargo vehicle, the driver experienced vibration dose values of frequency weighted acceleration above the limits during all three experimental tests, with a maximum value of 26.802 m/s2, whereas the results in the case of the armoured personnel carrier are below the 5 m/s2 limit imposed by the ISO 5349-2 standard. From the developed tests it was observed that, to protect the driver against the fatigue induced by the vibrations of the vehicle body, it is necessary to provide an elastic and also damping linkage between the vehicle and the driver’s seat. This is the only way to ensure the needed protection and it is, by far, the least expensive.

Bullets, shrapnel, and IEDs; all are dangers for infantry. Modern military forces have designed a new generation of versatile and lethal weapons systems to help protect soldiers from the dangers of battle: Infantry Fighting Vehicles.

Background In November 2008, a surgical team from the Red Cross Hospital Beverwijk, the Netherlands, was deployed in Afghanistan for three months to attend in the army hospital of Kandahar. During their stay, four incidents of armored personnel carriers encountering an improvised explosive device were assessed. In each incident, two soldiers were involved, whose injuries were strikingly similar. Case presentation The described cases comprise paired thoracic vertebral fractures, radial neck fractures, calcaneal fractures and talar fractures. Moreover, the different types of blast injury are mentioned and related to the injuries described in our series. Acknowledging the different blast mechanisms is important for understanding possible injury patterns. Conclusion From this case series, as well as the existing literature on injury patterns caused by blast injuries, it seems appropriate to pay extra attention to bodily areas that were injured in other occupants of the same vehicle. Obviously, the additional surveillance for specific injuries should be complementary to the regular trauma work-up (e.g., ATLS).

Textron's [TXT] Marine & Land Systems (TM&LS) unit said yesterday it received a $31.6 million contract award from the Army Tank-Automotive and Armaments Command (TACOM) to provide 28 COMMANDO(TM) Advanced Armored Personnel Carriers (APCs), with 40mm/.50 cal remote turrets, to the Colombian Army (COLAR). Initial APC deliveries to the U.S. Army, for shipping to Colombia, are expected to begin in November, with all vehicles scheduled to be completed and transferred by April 2014.
