"Get first aid here" radio command?

[duhrickjames]

How do I do the "get first aid here" and "get supplies here" commands for medic/support. There's also a "sector clear" radio command I'm not finding. PS. I'm new.

first aid and supply thingies are done automatically when you throw down health packs/ammo boxes. you wont hear them if you throw them but others will.
dunno about sector clear.
