The ceremony for the receiving of the remains of a soldier, while not a funeral, commands the same level of respect and reverence. In most scenarios, standing with one's feet together connotes a demure, beta, low confidence or low comfort emotional tone - but not so when in paying our respects to the deceased. Note that the two servicemen closest to the camera have their feet together, as does the person standing behind the casket (only feet and top of head visible). Certainly military protocol varies from country to country, however the "feet together and parallel" position is a universal body language sign of respect - military or civilian. The remaining serviceman (furthest in the row) is standing with his feet apart, positioned obliquely, in a more relaxed configuration - and thus in this setting he's sending nonverbal signals of aloofness, non-engagement and disrespect.
