I was reading this article in the news: 4 soldiers drown in Afghanistan Does anyone know (and is at liberty to discuss) what the soldiers were likely to be wearing/carrying when their vehicle hit the water? With just that equipment on, how bouyant is the user? How quickly can a trained soldier ditch their equipment to become neutrally or positively bouyant? Are the soldiers more likely to have drowned because of the fast flowing, strong currents, because they were stuck/incapacitated in their vehicle or because they were encumbered by the gear they had on? 4/4 dead from the same vehicle seems a bit too high a fatality rate to be just random circumstance (e.g. being knocked out on impact, wedged in or a weak swimmer)...it points to some consistent cause of death in their case (like encumbrance or a serious impact). If the Ridgback can't keep water out, does that mean it is not suitable for operation in a NBC environment? Or are the two not equivalent? What lessons can we learn from this incident? Is there a need for more bouyant equipment (this incident though tragic seems too one-off to consider adding more gadgetry to the soldier), better NVG, some kind of automatic pathfinding for vehicles at night or in poor visibility, etc..? Thanks.
