Typically “no field duty” or “no overseas duty” and other general comments are not appropriate for use in an official profile. Soldiers who are pregnant can get profiles that state no field duty or no overseas duty as a result of their pregnancy, but usually the profile will focus on what the Soldier can do as opposed to what they cannot.
The doctor writes the profile but the commander determines what a Soldier will do. Typically a commander will not go against a doctor’s recommendation. I would suggest you have the Soldier return to sick call and have the profile rewritten to be more specific.
As a side-note, be realistic. If the Soldier is broken, don’t provide them the opportunity to hurt themselves even worse or endanger others. I recall having a Soldier with two broken legs. I recommended he stay in the rear during an FTX. The commander insisted he come to the field. This was the old Army, we did not have hardstand or tents. It rained so hard during our FTX that he had to put his legs in trash bags to keep the casts dry. That evening, he slipped in the mud on his way to the field latrine and broke his arm. Hmm… guess he should have stayed in the rear after all.
