So none of those listed mechs possess the ability to aim their weaponry at the ground? I'm pretty sure that they have the ability to aim their guns at the ground.
Being able to "aim at the ground" is not the same thing as being able to "aim at one's own feet" - and even those 'Mechs with full actuator sets in both arms cannot do the latter.
In fact, now that I've double-checked against the above image (from Smurfy), the LCTs are the only 'Mech that can pitch their arms downward (or upward) by more than 50 degrees, with most 'Mechs being unable to pitch their arms downward (or upward) by more than 40 degrees.
For most 'Mechs,
θ (the complementary angle to the sum of torso pitch & arm pitch angle) is going to be on the order of 40 degrees (since most 'Mechs can pitch their torso down by 20 degrees & can pitch their arms down by an additional 30 degrees; 90 - 20 - 30 = 40), and
h (the height of the 'Mech's weapons from the ground) is usually going to be on the order of 6-9 meters if the 'Mech has elbows, so the distance
r (the closest distance at which it can hit the ground) would be on the order of 5.04 meters - so there should be a roughly 10-meter-wide circle around most 'Mechs where they would be incapable of hitting the ground.
(The
Locust, with its 60-degree arm pitch angle on top of its 20-degree torso pitch angle & an assumed height of approximately 8-9 meters, could reduce the diameter of the circle to approximately 3 meters - it couldn't shoot its own feet, but it comes close.)
The A-Pods (and, eventually, B-Pods?) could then provide a 'Mech with protection against any infantry (or Battle Armor) consumable that is dropped within the circle where it just can't aim low enough with its normal weapons and begins attacking the legs (the equivalent of a TT "leg attack").
