I had personal similar experience myself on exercise during NSF
days.
I was leading my platoon one night. Lead platoon ahead of the
company. Night movement in Ulu Sembawang. Walking along a kampung
track. Suddenly point man stopped and word was passed down that he
suspect enemy ambush ahead. I went up to the point and indeed saw
movement of enemy in the front at a junction. Decided to move back
down the line and report to the OC.
In my excitement, I was doubling back , I fell into a BIG PIT in
the middle of the track. How it got there, god knows ! Anyway, the
worse was that it was raining during the day, the PIT was full of
muddy sh...it ! This was of course in full view of No. 2 section ,
which was where they had taken cover nearby. I pulled my muddy self
out of the pit... M 16 was all covered with gooey mud... I was
covered in mud up to my waist. All around, I can see white teeth
flashing in the night. The guys were having a good (silent )
laugh.
When I reported to the OC in my state, he also broke out laughing
!
