[Spaceships] SS Mecha vs. HT/UT Tanks, and 'ships vs. jets

[Langy]

Any situation where one-hit-one-kill weapons exist reguardless of amount of armor. If man-portable anti-tank weapons that can blast through a tank's frontal armor in one hit are commonplace, then a mech that can dodge better than a tank but carry the same payload is definitely preferable to a tank.

If you don't need to carry the huge payload of a tank, a battlesuit would be even better than a mech.
