When playing Survival it quickly becomes apparent that the health of the standard enemy soldier goes up either per round or per-so-many rounds.
Does this also apply for the Juggernauts? I usually kill them with C4 and at first I thought it always takes 7 C4 stacked to kill the first Jugg that I get.
However Ive sometimes killed a Jugg with as little as 5 C4 packs – So now Im aware that how close they are to the packs themselves when they blow is a major factor in how much damage they take. Unfortunately this has also completely derailed any idea as to how much health they have and if it increases or not as you continue to progress through the survival waves.
Best Answer
ALL enemies get tougher as the game progresses to higher waves.
This video shows what is possibly the highest legitimate waves that anyone has gotten to (wave 153):
By wave 120+, Juggernauts can eat 5 Predator Missiles directly to the head and survive, compared to a single missile taking out a wave 6 Juggernaut. Looks like even the regular FAD-armed enemies need 30+ bullets from an LMG to kill. Fortunately despite their increased toughness, flashbangs still stun them as long as before.
By that time, the vastly higher total damage from the Airstrike marker barrage makes it much more useful than Predator Missiles.
