Guns depend on your playing style for example I like to rush spawns so I use PDW and scorpion if you sit back and defend AN-94 and type 25 Overall the best gun is the PDW 50 bullet clip kills quickly put long barrel to increase range and fmj to increase damage and it is BOSS.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
