Boy, it's awfully hard to tell from that picture. Do you have anything bigger?

It's even difficult to discern if they're holding M4s or MP-5s. But, it appears both may have magazines inserted in their weapons.

i concur with your observations as well...

Zooming in, looks to me like they’re empty. Not an uncommon bureaucratic response to such events.

I see foregrips on M4A1’s, but no mags. Army doesn’t use MP5’s unless they are SPECFOR. But I’m sure they’ve got mags with them. It only takes 1-2 seconds to pop a mag and chamber the first round.
