In geomorphology, a col is the lowest point on a mountain ridge between two peaks. It may also be called a notch, a gap or a saddle, although the last-named usually has a wider meaning and may contain a mountain pass. Moreover, the term col tends to be associated more with mountain, rather than hill, ranges.
Colonel (abbreviated Col., Col or COL and pronounced , similar to "kernel") is a senior military officer rank below the general officer ranks. However, in some small military forces, such as those of Iceland or the Vatican, colonel is the highest rank. It is also used in some police forces and paramilitary organizations.
