It's often referred to as 'FASA Physics' and the like. The Classic Battletech forum often uses the term 'FASAnomics' to explain the way Houses spend so little on their militaries and a single lance of 'mechs (and a light one at that) can take and hold a planet with a population in the millions.
It's not intended to penetrate. That's the thing. Vehicles- and especially 21st and 22nd era ones- suffer this liability. 'Mechs do not. Hence why crtiical hits can be hit when armour is remaining, especially 22nd era or earlier armour.
Putting enough 'primitive' armour on a 'mech so it has a BAR of 7 allows any weapon that deals 7 damage or more to 'penetrate' and obtain critical hits. Modern armour needs to be removed to a sufficient degree for critical hits and internal damage to be done.
Hence the shift in weapon philosophy. Weapons are designed to weaken the armour as much as it can in a location.
And that's why real world guns don't compare to what exists in Battletech. They don't play by the same rules- Gauss Rifles in space combat exceed speeds of Mach...15? 16? Something like that- and yet an Aerospace fighter can easily shrug them off because they have armour that's a few mm thick.
Battlemechs use very similiar armour, that can also easily stop such weapons...yet if they fall down, the armour shatters like glass.
Which makes no sense either way...
that falling mech essentially experience localized pressure equivalent to having explosion shockwave in your face, which means a single detonation of an explosive charge in front of the mech would just shatter all it's armor then from the pressure blast if by simply falling it can shatter it's armor since it's weight is incredibly light for something of it's size (yet another anomaly in BT, 14m tall and it weigh less than 100 ton? whatever they are using is practically aluminum class light).
If the armor is being hit by non penetrating weapon for example, and it's taking damage still either way even without penetration then essentially the armor is ablative... but this makes no sense when related to physical projectile especially since ablative armor NEED THICKNESS to work properly, thin and ablative is illogical since that gives the lowest possible capacity to stop an incoming threat.
