Movement to Daylight

I just returned from the latest leg of 2ID's (2nd Infantry Division) field exercise, and we did something called a "movement to daylight". The idea is that instead of sleeping at night a rifle platoon stays up walking till the sun comes up or engaging the enemy. We did both. My platoon is populated by young American super men so we crushed the enemy everywhere we saw him. I am completely serious. One young man single-handedly destroyed 6 enemy tanks. Especially remarkable, since he is considered to be the weakest member of the platoon. Granted, he cannot even carry his weapon, the Javelin missile launcher, into battle; but once there he is deadly.
To be perfectly honest, I haven't been myself lately. I feel as if I have been ill since I set foot in Korea and my body is showing signs of wear and tear. Walking for eight hours in sub-freezing weather and not sleeping was a particularly cruel thing to do my body. My body returned the favor by giving me excruciating cramps in both my inner thighs. I was nearly completely debilitated since I could not extend my legs and thus could not rise off the ground. Believing myself to be dehydrated, I ripped my shirt off and administered an IV to myself with the help of three NCO's in my rifle platoon. After some consideration, I realized that dehydration wasn't likely since I'd been guzzling fluids all day. The pain was just from disuse and not stretching my muscles at all. Fun.
