It seems to be taken for granted that a modern infantry squad or platoon is far more combat effective than one operating in previous eras, such as World War II. However, how much of this is actually true when considering one squad or platoon in isolation (that is, lacking air support, AFVs, and other such factors)? A M-16, for example, has a far higher rate of fire than a M1 carbine, but how does this actually translate into combat effectiveness? Likewise, a modern SAW is probably more accurate than a BAR or MG-42, but is this difference really that substantial?
