Field ops:
- Ammo packs become grenade packs, with cooldowns and maximum amounts adjusted to balance. Could even make the grenades weaker than the ones you start with.
- No artillery or airstrike, instead a smoke grenade. This smoke grenade last short and has a limited range compared to the smoke strike from the field ops speciality in the original post.
A class specialised around (less lethal) grenades as well as smoke really focusses on disrupting the other team’s plans and forcing them to relocate when they don’t want to.
