Harris \'sitting up a tree\'

A couple of miles further they came to a river. Smegg said that
signals show that it ran almost exactly to their target point. They
could ride their JMC inflatable rafts all the way up and could bring
them there before sundown the next day. They decided to camp there
for the night and head out the next morning.
Harris sat in a tall tree with his back pressed against the truck.
He loaded a flash grenade into Lloyd's grande launcher and primed the
weapon. The only thing Harris wanted right now was a auto-feed for
the grande launcher to save on loading time as he was sure here ever
second was going to count.
All that was needed was to replace the killer furballs with killer
robots and giant snakes, and it was the first away mission again. A
unknown planet, no idea what to expect and both the captain and first
officer planet side. Harris was going to give White Wolf an ear-full
over that, endangering the lives of the senior staff, that if they
got out this one alive.
Harris began to sharpen the combat blade he was carrying, the sound
seemed to echo through the darkness of the night.
