Secret weapons BF1

Greetings,

i wonder if i can request to unlock some of the secrets weapon in battlefield 1 , cause i wonder why EA would hide such thing from premium owner's and what is the main reason for not making it simple to unlock 

the weapon that i want to be unlocked such as 

The Peacekeeper.

and there is a weapon which been gifted to those who pre-orderd the bfv 

i'v managed to unlock some of the weapons such as the broken bottle along with some dogtags.and i understand that the rest need to have some players with u to unlock it such as an omen ect...

ill be glad to be helped ....
