Should i forego EOD reclass for the the opportunity to be a part of an SMU?

Go ahead and apply for the SMU, you probably won't be selected. Those emails are auto-generated to everyone in the Army who meets certain criteria - usually GT, MOS and clearance
Especially if that SMU is USASED or JSOC, don't expect to be hired on your first application. It's even part of the briefing that they give, most people will be rejected the first time and told what they can do to be more competitive on your next application. Part of it is that you're a relatively new NCO.

The application process takes about 90 days. Send in your application, if you're approved then drop your EOD class. Absolutely DO NOT drop your EOD class just to submit a SMU application.

I’d go EOD, but that’s just a personal choice. Everything you do has short term and long term actions. Choose whichever is going to get you closer to your overall big picture goal.

Can you reclass and eventually go SMU. Graduating the EOD school is a big door opener in the military and post military.
