Agreed with Tnargraef. Grineer lancers/troopers/javelins only pop out to fire if they can see you from their cover zone but from time to time the pillars in the level are shaped in such a way they don't see you at all and as a result they just sit there. If it seems dead silent for even one second, do a victory lap around the pillars just to be sure there isn't a muppet sitting in the wrong place.
