As part of the upcoming "new player buff". Everyone will get a few things for free.
These include weapon attachements (laser sights, forward grips) depending on the gun, the 50shield utility item, and suit slot upgrades for all classes.
The suit slot thing for Medic and Infil will be something new, but the LA, HA and Engi will get those 3 maxed out by default. And according to wrel we won't get refunded for those. So if you're like me and could use those few thousand certs for other things...
