Where? (I believe you but I'm curious now).
Basically only in ST:ID, in the starship duel both in and out of warp. But arguably also when strange powers made the raygun beams go astray in TNG, such as in "The Last Outpost"... Whether this would be a controllable option for hand phasers is unknown.
Again, I believe that's true, but at what cost to power consumption? Sounds like this would cost a lot more than the regular 'stun the enemy at 10m distance' setting. We almost never see those phasers deplete but they ultimately would be. So all you'd need to do as the bombarding party is keep them trapped there - which I'll admit might be impossible with those phasers. So those redshirts would need to be on the move, while continuously blanketing the region of the air those incoming shells are coming from with those phaser shots to defend against the supposedly saturation fire of their WW2 foes. Not saying it's undoable but even with their phasers it might be kind of hard to keep it up all the time while they're running towards the enemy that's supposedly at least 10km distant.
I gather the superpowers of this supertech would need to be utilized creatively there. The redshirts could close the distance by walking underground, say...
A lot depends on when the power runs out. "Armed with a phaser" might involve looking like Pancho Villa, with fifty power clips in bandoliers across you chest.
It would have given them a lot of tactical advantage in countless direct person-to-person phaserfights we have seen but we rarely see it there. Unless of course, those 23rd/24th century soldiers carry some nullification devices that essentially eliminates this autotargeting so they'll have to resort to hand based aiming again. If that is true, then yes, they would have another huge advantage on the WW2 party.
From what we see, the phaser sidearm is the ultimate quick-draw weapon: typically minimally holstered, frequently fired from the hip, and unerringly dropping the foe at twenty paces. This would more or less call for autotargeting, or then Arvo Ojala level superskills for each operator.
But perhaps the weapon is optimized for this use? Its shortcomings vs. WWII slugthrowers are obvious: low rate of fire, required dwell time, the bright line pointing straight at your firing position. Fighting against WWII troops would be a type of dissimilar combat all right, but the advantage might not so obviously go to the redshirts after all.
Well yes, if they actually decided to subjugate a WW2-era planet for some reason they of course would be having the additional advantages of transporters, shuttles, and probably a Starship with photon torpedoes for orbital bombardments, too, and anything more they could have at their disposal. But here, I'm just reacting to the statement where it was said that 100 guys armed with phasers (and presumably nothing else) could defeat an entire WW2-era world.
Hmm. Defeating the world would probably be easier than defeating its armies, when you possess the ultimate stun guns...
A hundred guys with concealed sidearms would be a big threat if
not pretending to be an opposing battlefield army. Instead, they could walk into cities and then stun tens of thousands long before any sort of a response could be mounted, take control of institutions and assets, and dig into undefeatable positions behind human shields millions thick.
