Observation
The PF-89 has a simple optical sight for aiming, with no night combat capability. The firer must be able to see and identify the target and estimate the range to it. The round of ammunition is self-contained in a disposable launch tube. The system weighs only eight pounds and can be utilized effectively with minimal training.

Famous quotes containing the word observation:
“Nor has science sufficient humanity, so long as the naturalist overlooks the wonderful congruity which subsists between man and the world; of which he is lord, not because he is the most subtile inhabitant, but because he is its head and heart, and finds something of himself in every great and small thing, in every mountain stratum, in every new law of color, fact of astronomy, or atmospheric influence which observation or analysis lay open.”
—Ralph Waldo Emerson (1803–1882)
“I know not anything more pleasant, or more instructive, than to compare experience with expectation, or to register from time to time the difference between idea and reality. It is by this kind of observation that we grow daily less liable to be disappointed.”
—Samuel Johnson (1709–1784)
“He is one of those that deserve very well, but are very awkward at putting their Talents within the Observation of such as should take Notice of them.”
—Richard Steele (1672–1729)
