An edge case today prompted a thorough review of the standing from prone rules as described in BMM. My Kit Fox W ended a turn at 10 heat (i.e., -2 movement points), prone, and missing a leg. Under BMM rules, it is not perfectly clear whether or not I would be able to attempt to stand with one leg despite the heat penalty. BMM's description of standing from prone with one leg follow many of the same prerequisites of using the Minimum Movement rule, but do not explicitly state that standing from prone with one leg is a variation of using the Minimum Movement rule.

The rules on p. 19 state:
Quote
Leg Destruction: A prone biped ’Mech with only one leg (or a prone quad ’Mech with only two legs) may still attempt to stand. However, it may only make one attempt per turn. This attempt to stand is always considered running, and can still be made even though a ’Mech with one leg can normally only walk. [...]

Minimum Movement: A prone ’Mech with only 1 MP available can use this rule (see p. 16) to make a single attempt to stand.

The separation of the Minimum Movement rule from the standing from prone with one leg rules implies that they are separate, despite many of the same conditions applying to the prerequisites to standing from prone (running movement required, only one attempt allowed, a note that it can be made even though the 'Mech can normally only walk).

p. 44 does not make it clearer:
Quote
A prone ’Mech with one leg may attempt to stand on its remaining leg in subsequent turns. However, it may only make one attempt per turn, and this attempt to stand is always considered running. In an exception to the normal rules, only one PSR is required for this attempt, even if damage or other factors means that the attempt would normally require two or more PSRs (though all modifiers from any such factors still apply). If the ’Mech manages to stand, it has a Walking MP of 1 (this overrides all MP increases) and cannot run.

My interpretation of these rules is that standing with one leg is *not* determined under the Minimum Movement rule and is instead an action that is allowed independent of the 'Mech's current MP, as the two actions are so similar in requirements that if it was a form of Minimum Movement, the rule would simply be written as "A prone biped 'Mech with only one leg [...] may still make one attempt to stand per turn under the Minimum Movement rule." By extension, I'm also interpreting this as stating that once the 'Mech is upright (assuming a successful PSR), it has 1 Walking MP for that turn and all subsequent turns, which is affected by heat and allows it to then make Minimum Movement moves (i.e. into water, up/down hills, into woods, etc.).

However, if the 'Mech is always reduced to 1 MP upon losing a leg, even while prone, and standing from prone with one leg is an action that falls under the Minimum Movement rule, then a 'Mech with one leg cannot enter a new hex on the same turn it stood up, and having a Heat value of 5 or higher will prevent it from attempting to stand from prone entirely.

Which of these interpretations, if any, is correct?

Excellent, this is much clearer. Aside from the now-missing Quad 'Mech wording, the draft errata looks great!
