let's not forget one of the more amazing pieces of work by an individual:
And that skinny farmer? Well, he picked up his iron-sighted Finnish copy of the Mosin-Nagant M28, sewed himself an oversuit of white bedsheets, and (with the occasional judicious application of a KP-31 submachine gun) proceeded to personally turf between 500 and 700 Soviet solders in front of Saint Peter's desk until 06MAR1940 when a Red counter-sniper got lucky and put Simo Häyhä out of the fight for the rest of the (all-too-brief) war.
And, if I remember right, he managed to pull himself back up, spot, and kill the Soviet who shot him.
Horribly outnumbered, pushed to near-exhaustion well before the end, the Finns still kicked the crap out of the attackers through the use of their brains and courage and skill.
