Trying to decipher that foul odor

What is that smell?  Walking around the base here in Basra, I can smell something bad. I just can't put my finger on it.

Is it the chow hall? Probably not. The food isn't great, but it's not that bad. It could be the dumpsters that are prepositioned just before the entrance to the chow hall. They sit in the hot sun all day and radiate horrific smells that do nothing to entice diners before their meals, but I'm nowhere near the chow hall.

Could it be the incinerator? There's no land fill here, so we burn all of our garbage (which the Army has determined could be harmful to the health of soldiers, but only for the short term that they're deployed).  Maybe, but I don't think the incinerator is actually running right now.

Maybe it's the smell of soldiers at the shooting range. The combination of the gunpowder and oil and cleaning supplies for the weapons creates a unique odor. But I actually enjoy that particular smell.  That's not it.

Perhaps it's just the general odor of Basra.  All of these aforementioned olfactory stimuli could combine to make a somewhat discernable yet objectionable smell. I guess it's a possibility.

As I make my way back to my room and remove my uniform, I finally realize what the smell is. BO. That smell is me. As I collect my toiletries and head to the shower point, I think about how gross it is that I can smell my own sweat with little effort.

Oh well, at least I know what the smell is now.
