Oh, does anyone know the buff effects for the medic drop? I didn't find much of anything in the ability files
Edit:
Thanks to Milkacow's help

here are the values and the location (\attrib\ebps\props\supply_drop_medical_supplies.json).
The buff and heal have a range of 25 and last for 30 seconds. The heal restores 27 health.
Buff for all infantry and HMG units: +17% armor, +17% accuracy (multiply_add).
Buff for all AT guns: +17% armor, +17% damage (multiply_add).
Buff for all mortars and artillery: +17% armor, +17% damage (multiply_add).
According to Milkacow, the effect stacks not only with other effects but also with itself (because it is set to not be exclusive and because of the multiply_add usage type), so you seem to be able to pick up all three for a +51% bonus but then you probably lose some of the healing power.
