Squad points and ranking up. Best method is the following.....

How to earn:
Level up get 2
Completed Field Order 1
Operations challenges, also a bonus for how many you complete. You can buy more on top.
Weapon challenges 10/25/50/150 kills no attachments one point. Anything for camos or challenges.
3,000 XP = one point.

My advice would be to play squads using specialist loadout, I have been getting ones on and off in that mode on top.
Avoid buying perks/weapons until you maxed out the number of class slots first. Do not buy more people the squad.

When you buy another person pick convert ops I believe it has the higher perk valve for squad points in the game also dead silence/off the grid nice to have.

Pricing
6 to 10 for Guns
6 to 15 for Perks
3 to 6 for attachments

When you do the maths the best way is to do the above method you can share points across people but not weapons. Having one person maxed allows you to unlock stuff for the others so you're not naked.

PS

I wasted 24 points so far until I worked this out yay

Updated you gain 1 per every 3,000 xp.

i dono about you but if you play and don't suck ass you will have alot more then 500 points before u even get close to 10 prestige
