Took his task to heart...
Thought this was worthy of a re-post. It was said Simo would hold snow or ice in his mouth to cut down on the telltale "steam" from his exhalation and that he stuck to iron sights in order to lower his profile. Ingenuity can carry you far folks....
I give you Simo Hayha (The White Death, as he was known to the Soviets)
During the Soviet invasion of Finland circa 1939; this 5 foot 3 inch farmer served as a sniper in the Finnish militia. He conducted his duties alone in the harsh winter, armed primarily with an un-scoped Finnish variant Mosin-Nagant. Was this one man effective? 705 dead Soviet soldiers will endorse his efficacy. By the way; he accomplished this task in about three months time.
The Soviet army was so terrorized by this small man and his little rifle, that they eventually tasked an entire battalion to hunt him down.....to no avail. That's an entire battalion tied up with one partisan......think about it.
One could say he ended up being a one man psychological warfare unit as well.
When asked later in life how he became such a good shooter, Simo simply responded...."Practice".
Don't ever count yourself out because you don't have the best gear or are feeling past your prime. Take Simo's advice and practice.
