So… I got the battletech total war and techmanuel books and made some dumb stuff.
This thing walks around 51 m/s and runs a small 74 m/s (102 m/s if the MASC is engaged). It can’t do much besides be fast, but if you ram something oh boy does it hurt. That’s why this mech is called the missile. There’s weight left for a grand total of eight points of armor (more if you wanna invest in ferrofibre for some reason) or a singular small laser (possibly a longer range model).
The main thing is that with MASC you can reliably move 25+ hexes to get a 6+TMM. With some positioning you’d not need armor, as your speed is your armor.
For those who don’t know, in battletech you roll two six sided dice and total the results. There’s a minimum you need to roll to hit (for IS usually a base of 4, with modifiers). So end your movement in a light or heavy woods with at least another light woods between you and adversary’s and you simply cannot be hit.
It’s exceptionally stupid and a waste of BV (even if I haven’t yet calculated it’s bv worth) and will die to the first or second hit, but good luck getting that hit!
