After the update 1.44 was added new animation of treatment. New animation is good, but unfortunately, treatment not looks good, because:

1. wounded soldier, is not responding to treatment. (not stops, not crouches)
2. the distance of treatment is not fixed. (medics do treatment in emptyness or head-to-genitals)
3. direction to injured target ignored. (medic can treat, with his back to the target)

Please teach the AI to react to the any allied contact!
I before reported about it here: http://feedback.arma3.com/view.php?id=24040

If the medic uses treatment, then wounded soldier must stops also in kneel position(like medic) and then manipulation of the doctor hands, will be at the height of the torso of a wounded soldier. Also you should reduce and fix the distance to a more closer. Also rotate the medic to the wounded man should always be taken into account. In this case, the treatment in the game, will look more realistic and much better!
