Wow great forum, lots of good info here. I am a BM1 in the USCG and am interested in obtaining a 3M Unlt while in service. After a bit of research I figured the best way for me accomplish this would be to obtain an AB license and then attend PMIs AB-Mate program. My question is, is it required to have AB Unlt as a prerequisite for 3M Unlt, or would any AB count as long as you have the required time u/w for 3M Unlt? I couldn’t find specifics on this. Thanks.
