Beyond buyout / transfer and bio fix

How does it .....

"reducing losses suffered by your forces while defending"

You lose less units.

Sliding scale based on qty

Has anyone got the data on % reduced loss based on % of tech?

I'm not sure but base for attacking is 8% loss, if you have 1m units and attacker sends 1m units you should lose 80k just like they lose 80k is what I think. so if you have 75% medical you would lose only 6%?

does it help reduce the amount of troops you lose when demo'd

it only helps reduce losses on being attacked, being dissented out of a military is not a medical issue.
