85 degrees–85 pounds on your back—85 percent humidity—25 miles to hump=priceless.
Here's some stuff I remember:
Nipples getting all raw from my flak jacket rubbing against them for three weeks.
Prickly heat all across my back in Panama from my rucksack
In the showers at Camp Pendleton after a 25 mile hump and a Marine keels over with heat stroke. (Lucky we had plenty of water)
On top of a mountain at 29 Palms at night in an OP during the winter. No cold weather gear because the trucks got assessed as battle losses and sent back. Then it snowed.
Sitting in a fighting hole back to back with your battle buddy in a driving rain storm at night. There's only one tiny dry spot between the two of you, down low on your backs where the water hasn't yet run down the collar of your Goretex.
At JRTC when I was a platoon sergeant (98) we were supposed to block and defend an intermittent stream with a road leading down a wooded hill during the mechanized attack portion of our rotation. We had three trucks loaded with barrier material that were (you just guessed it) knocked out by enemy air. So only one truck load showed up for the Mine Wire Obstacle, which was templeted to be about 200 meters across. We were also supposed to get a blade, which finally showed up from the enemy side of our position after we caved in the stream by hand. Luckily, the engineer was a moron and got the dozer stuck in the stream, which meant, if the enemy tanks attacked down the road, they'd be halted by the stuck dozer.
Long story short— the tank company did come down our road, and we knocked out the first two with Dragons and called in a Fascam on the rest. After it was over and we were doing the AAR, my senior O/C dinged the hell out of me in front of the platoon for the MWO that wasn't build to standard. He went on and on about how many mines were supposed to be laid in depth, triple strand concertina, etc. So I replied, "I understand that sir, but the trucks with all the class IV got knocked out and we only got one instead of four."
He goes, "I'm just telling you your obstacle wasn't built to standard."
My reply to him, "Should I have just sent the truck we did get back and not build an obstacle at all?"
