Pictured are six Marines with their Chaplain (AG Chaplain Williams) taking a moment at an outpost overlooking an active battlefield (somewhere in Afghanistan) to pray for themselves, their families, and their comrades out in the fight. They are taking a moment to participate in one of the very freedoms that they fight to protect.
Marines stand this post 24 hours a day, 7 days a week, in both freezing and brutally hot temperatures without the luxury of hot food, running (or warm) water, electricity, any way to communicate with their loved ones, etc. The only way to get there is by traversing a two foot wide path cut through a mine field along a mountain range -- which Marines do constantly in order to resupply themselves with mission essential items.
They do this while being reminded daily of the dangers of their works as there are two crosses that stand just outside of view of this photo that bear the names of those that have paid the ultimate sacrifice in this area.
