Only 29 pounds.
Imagine carrying that brute very far. The old ones were fully automatic and if you have shot a 30-06 you know that is a beast round and I can't imagine letting them off the chain fully auto, but maybe being that heavy the recoil is manageable. On the other hand, remember that men back in WW I and WW II were much smaller than today and they were lugging these things around.
I am sure that our new, more diverse and gender equitable military would handle these no problem.
