To test the security of the tunnel, I proceed through it noting any possible shortcomings of using this route.
At the tunnel site, I do note a possible water go-around should the tunnel be unsuitable. It's favorable for light watercraft, but not wide or deep enough for battleship or submarine use.
Moving along, I come across another possible fortified observation post. It appears to be unoccupied, so with caution, I take some reconnaissance photo's noting the strength and weaknesses and coolness of this position.
Since the site is unoccupied and light traffic, I decide to take a break at the fortified observation post before proceeding to the dam.
After the break, I proceed to my first objective for the day.
Here I take some photo's of the dam noting the condition of the dam as well as any occupying forces.
