unemployed persons receiving GI bill on monthly basis with o

Hi, I was awarded a small claims judgement against someone that is unemployed and only receiving monies from a GI bill. If I issue a writ of execution to garnish someones bank account will it be able to garnish the account if the only monies available are the ones that were issued from their GI bill (GI bill is direct deposited every month)? Also, the person deposited a money order from me a couple of months ago, can the bank take that deposit into consideration as income if they are unwilling to give me money from the persons GI bill deposits?
