To elaborate more on what Major Gronovius said:
If I'm not mistaken, and I very well could be, the "Dragon Modern US Figures" is a series, not a particular set.
For instance they have, "US Marine Tank Killers," "US 101st Air Assault Screaming Eagles." US 82 Airborne," "US Light Infantry," "US, Special Forces," and "US Sniper Team," just to name the ones on my shelves now.
All of which are depicting modern solders, wearing modern equipment, and carrying modern weapons. Including but not limited to, M4s with Aimpoint scopes, SAWs and modular, internal frame ruck sacks.
