Read the thread - Episode 1, Chapter 3 lets you boost this. Start the level, watch the cutscene, kill the first sniper crawler almost straight in front of you (and one or two other crawlers while you're at it), Restart Mission (don't end it), watch the cutscene, kill the first sniper crawler ... You get @2 sniper crawlers per minute. It's boring so I do it while watching TV.
