Is this a armyworm

Thanks to another thread I followed advice and tested my brown spots for bugs.. 

 

Nothing much came from the dirt but this worm came from the surrounding grass clump at ground level...

 

I thought they ate the leaves, what ever is causing the spots is at ground level ..

 

Looking at pics on google me thinks it's armyworms .. am I right??

 

This is in Fescue hay fields.... 

 

I will reread the other thread for a possible treatment if this is in fact what's causing it, I'm headed back to the field with more soap & water now...
