I apologize if I have offended you.Could you please share your training and background to give us a perspective on your statement?
I didn't want to draw a giant flow chart of when to charge, retreat, shoot, reload. You don't need an MG-42 or that volume of fire to force your target to take cover. Obviously tactics change based on the immediate circumstances, and as the 4 rules of gun safety dictate. Pinning and flanking are basic squad tactics, that really don't take much skill.
Otherwise, I fully agree with you.
Absent a Squad/Team, it would indeed take some serious skills to win the fight.
