Dad's Army character (4)

I believe the answer is:

pike

(Other definitions for pike that I've seen before include "Fish; weapon; hill" , "Spearhead attached to a long pole" , "dive in this position" , "Old spear or voracious lake fish" , "Fish and pole with a spearhead" .)

I've seen this clue in The Guardian.
