YMMV. We're supposed to adopt a certain suspension of disbelief about the whole rationale of such things. However, sometimes there are things just just break that impression of credibility, mostly in the Real Robot genre.

That has got to be the most retarded mecha idea I have even seen. It takes everything about a portable gun and makes it a hundred percent more difficult! You fuckers couldn't mount it on a fucking TANK? Hauling that shit around removes the dubious mobility advantage of mobile suits in the first place! I get 'relaxed physics', and power sources with output way out proportion to their size, but... why is it that these awesum weapons are never mounted on something with a bigger sensor pack and dedicated ECM/ECCM? Am I supposed to believe in puny shoulder-mounted sensors? Perhaps so, but...
Arrgh.
Ground-to-orbit rifle? Oh fuck you. I could have entire arrays of the damn thing to swat ships out of the sky if I didn't have to worry about power feed, lack of armor, and keeping it mobile. Or I could just have a BO-... okay no. Keep calm. Remember the genre...
Military intelligence may be an oxymoron, but sometimes logic just flies out the window and not in an awesome 'Go Beyond The Impossible' way. Post those designs here, please. Super Robots get a blanket pass, and older anime may be excused simply for not knowing any better.

Oh god, it's actually a torpedo launcher. What.
