Are dual military both entitled to Family Separation Allowance (FSA)?

I am currently TDY (retraining to a different career field, will be here a total of 52 days) and my husband deployed a day after I left. Are we both entitled to Family Separation Allowance? I've heard a few different things (e.g. only the higher-ranking will get FSA, both members will get FSA, etc) and would just like some clarification or hear about cases people have gone through that are similar.
Side note: I will also PCS to a new base while he is still deployed, and he will have to return to the same duty location he departed from to out-process and then join me.
