UKF received the medic squad to encourage/accommodate more diverse builds (support weapons, Assault Sections, etc.) and because it's not desirable to force people to build a FORWARD Assembly in their base.
I'v got a partial counterargument for the diversity aspect: if we look at the two doctrines that feature ass tommies and at tommies we can see both of them has a halftrack. And coincidely these halftracks are gaining the ability to heal in this patch. In all other cases one would always have at least one medic IS to heal support weapons anyway.
I agree that with the recent fix UKF medics are indeed too cheap. Sure they can't reinforce like USF ambo, but that's their only non-doc healing platform and most of the times it sits in their base in smaller gamemodes. I believe it is more likely on the other hand that UKF medics sometimes would leave the base to capture some nearby sectors as risking their loss is not as serious for UKF as it is for USF.
As for a solution I would add some munitions to their cost. Not 60 as forward assembly but somewhere around 30 or 45. Or not even to the squad directly, but as an unlockable sidetech that allows the requisition of medics. Perhaps it could be 5-10 fuel instead in the latter approach.
