I'm reminded of the scene in Band of Brothers where the Regimental Commander reminded the Battalion Commander he wasn't supposed to charge out there and lead the Company into battle. I know that's not historical, but the point stands...
I'll say it does. Historically accurate or not, it is entirely realistic and, more to the point, believable.
There have been times where E-4s, -5s-, and -6s have said much the same thing. Back when I was younger, it would be a cold day in Hell before I let even a 2LT or SFC in front of me. It would have been a personal and professional embarrassment.
There are elements of personal and professional pride, self-preservation, and self-reliance at work here. Please note this is viewed through the lens and from the paradigm of an infantryman.
Besides, ridiculousness about Jaime Wolf aside, who would really want a forty or seventy (!) year-old leading an assault? Nah, leave the killing to the youngsters, and the heavy planning to those who have the experience, schooling, and training to do it properly. There is a reason commanders should stay, at best, one element back from the formation they are leading. It keeps them in the mix without getting bound up in it, lets them feel the pulse of the fight their unit is getting in, and allows them time to make the right decision(s).
Now, as far as 'Mechs (or tanks for that matter), I can see lance leaders leading from the front in certain instances--though I'd rather have a trusted senior/experienced MechWarrior still riding point in just about every situation. I definitely would
not want my company commanders literally leading the charge, if for no other reason than they would get shot out of their machine first, all other factors being equal. And what good does that do to the company, battalion, and regimental missions, let alone the eleven other MechWarriors behind him or her?
Battalion commanders should have no place trading shots during a normal operation. Maybe in some esoteric, last-ditch, Hollywoodeqsue scenario (e.g. the ragged remnants of Second Battalion form up to give the DropShips time to lift, say), but certainly not in some deliberate attack or defense; they should be monitoring the fight and winning it through delegation, not misguided personal heroics*.
*See the bombing mission in September 1943 over Stuttgart, where the group's commanding general's decision to circle the target three times let to, shall we say, deletrious results. And this was by a commander, BG Travis--a hell of a combat leader who did fly 35 combat missions as it happened--who was at the head of the pack. The decision, in this case, was not about personal heroics so much as professional requirements foisted on a man to accomplish what the bigger boss (Hap Arnold) wanted: a good result that could be used to foster the then-nascent daylight bombing campaign and to keep the heavy B-17s in Army hand, and in Europe. But the point stands--let the lower ranks do the fighting and the higher-ups figure out how to do it best. If Travis had not been along with the proverbial Devil breathing down his neck behind him, the raid almost certainly would not have been as costly as it was.
