If you just here to see if someone uploaded a video on how to kill the JUGGERNAUT easy,
Here it is :)
UPDATE:
If you dont get your achievement to pop then do what pogomax says:
EDIT.. shut game down went to achievements page CoD MW and they popped
and here is all 14 missions on Realism Difficulty (You can play on Veteran if you want)
Springbok NL in the comment asked about the difficulty in general, im not good in explaining things so i do videos.
i can try XD. I started on REALISM directly on this game and its pretty darn EASY. just a heads up, i have completed every cod on veteran (except some, infinite warfare, advance warfare and some others. i took a break from cod)
if you played the older ones and did it on veteran then you gonna have no problem on this game.
Checkpoints are given like each 10sec, im not kidding XD i get so many checkpooints on realism its a JOKE.
Realism: takes away you HUD completly and i must say it was enjoyable as hell playing like this.
also it is veteran diff but without the HUD and you do get allot of checkpoints.
if you after this achi then i suggest do it on realism if you really wanna feel like you there 0_0 it was awesome and great story. the game is really short thou, did it in 7h-8h on realism.
i started around 1800-02-30 XD i wanted to finish this as quickly as possible so i can focus
on co-op and MP.
