Your point was there are no hand carried weapons, but there are/were. And to my memory a Gauss has never been hand held. Arm mounted but not hand held. And tactics for using a rifle... Point (at enemy) and click.
Yes I can Imagine, I'd be a cyborg!

Well, when they taught me how to use a rifle, the first thing was to teach me to fire from prone position to minimize my profile. I was also taught to target my rifle without having to wave my whole torso or arms around. I was taught to shoot one weapon at a time, be it a G3 or a grenade or a grenade launcher. And when in cover, I was taught not to walk out of cover with my whole body (since well, my weapons were not torso or forearm mounted), take a potshot, then backpedal in cover.
I was also taught to never run in a field unless there was covering fire from my support squad. I was taught that as infantry, my APC unloads me on the field, I dig in, I stay there, because moving equals detection and death, unless under the cover of overwhelming suppressing fire.
I was also taught (well, not taught, but medical degree you see) that if I get a 7.62 then it's bye bye cruel world, one shot, one kill. That when any indirect fire targets me, be it mortar, artillery or heck, even iron bombs, I am dead. Wasn't taught anything about homing missiles, because well, those are not around for infantry yet.
All this is very valid modern battlefield knowledge. How any of this could apply to a Battletech setting, is beyond me. I believe the same goes for any modern armored warfare tactics.
That was my point, not arm or hand held weapons. In a setting where death comes in the form of a single rifle bullet or a single HEAT round or missile, tactics are very, very different than in a setting where death comes from the combined fire of an infantry and support company. Even more when you don't have to pay for repairs or a resurrection potion :-)
