>>6123342It's mostly the same spread as the grunt clone, so he has both the DC-15A blaster and the standard longer barrelled DC-15 along with an array of hands.
The hands is where things change up a bit. In addition to the red paint on the armor, the Captain also has a pair of spread out hands (pictured here) that aren't included with the regular trooper.
I'm very glad you asked that, btw, as I had assumed that the Captain had the exact same accessories as the grunt. Noticed the new hands only because I was double-checking to answer your question!
