Escalation upgrade tree?

Is there a list for the weapon upgrade trees for Escalation anywhere?

And perhaps more pressingly, what exactly are the grenade/pistol upgrades you can give when you spawn? When I get a pistols upgrade I don’t notice any difference. I have the same pistol I had before and the same pistol as the rest of the team.

If you are given pistols as a load out option, you are able to spawn with a Boltok or a Talon, but you still have to manually select it yourself. Similarly, grenade options allow you to spawn with grenade options you didn’t initially have.
