Patience is a virtue!
Intel says the enemy is trying to sneak in through the mountains. You and your team air drop in to track their movements for the next 10 days... It's now day 37...
You are completely silent, sometimes sitting still for days at a time....
Sometimes low crawling at an inch every 15 minutes...
You sneak up on the enemy and pick off one at a time, avoiding a massive firefight, hiding in the shadows, lurking to their flanks to pick off another.
You channel them into the valley where they soon discover they are in the middle of a mine field! Before the humans know it, they've lost their radio man, 40% of their troops are casualties, expended all their ammo shooting at shadows, and their armor transport has turned into a 60 ton road block!
They've suffered enough.. Take em out!
