Even during the most powerful hurricane, the coldest weather, the record breaking snow, members of the US Armed Forces are always on duty 24/7/365 guarding the Tomb of the Unknown Soldier.  

Although some of these photos of Tomb Sentinels with bayonets on their rifles were taken during a powerful storm in September, others were taken  during Hurricane Sandy. They demonstrate  the Sentinel's creed which in part says:

"Through the years of diligence and praise and the discomfort of the elements, I will walk my tour in humble reverence to the best of my ability."

According to the Society of The Old Guard's website, Tomb Sentinels "are completely dedicated to their duty of guarding the Tomb. Because of that dedication, the weather does not bother them. In fact, they consider it an honor to stand their watch (we call it "walking the mat"), regardless of the weather. It gets cold, it gets hot - but the Sentinels never budge. And they never allow any feeling of cold or heat to be seen by anyone."
