you know that BT combat space is heavy infected with ECM?
You probably heard of ECCM.

and as said only because Stackpole wroten nonsense about range in his crappy novels its not set in stone. combat range is only a question of game-play. Multi Kilometer ranges simple don't make sense because of the rule of cool - want to play with miniatures but have multi-kilometer ranges at scale? Want to shoot Mecha but again at several dozens kilometers? With "real" weapons a Archer might have a total of 60 missiles - each guided each with range of 30km or more, each missile will deploy EFP warheads over the target. And each explosive formed penetrator will likely break through all but the thickest top armor. want to play a computer game were you start in your mech do run some hundred meters before getting wasted by another guy - that didn't even have seen you just fired some dozens of his LRM at your position?
The kind of missiles a mech would hold, are going to be only like MANPADS, and only able to hit an aerial target up to 10 kilometers away. Note I said aerial targets. Tank cannons can hit over 2km distant, but your target is going to be pretty small. In relation to a mech, such a weapon would have to held like an external rifle, not unlike some mechs in the Gundam universe.
A viable excuse for AC and UAC short ranges is because the cannons, in order to fit inside a mech, would have to be short barreled and use smaller amounts of propellant. Because penetration and damage is equal in all ranges, mech ballistics are surely using HEAT. Otherwise, you would need an armor piercing mechanic, with AP successful penetration --- able to cause damage --- in direct relation to the distance of the target, along with a damage curve that is proportional to distance, factored with the thickness, layers, and slope of the armor. Missiles will also be using HEAT.
Because of HEAT weapons, mech armor will have to force HEAT weapons to explode outside of the armor via explosive reaction, or ERA. But ERA gradually expends itself, so this reflects the gradual diminishing of HP of a mech armor. Thus the relationship of HEAT vs. ERA can be simplistically expressed in HP. Mechs have their armor repaired by mounting new tiles of ERA.
Despite the multi-kilometer ranges, LOS prevents realizing full range potential in anywhere but the open field, but realistically, there should be no range difference between a machine gun, a 20mm cannon and a 50mm one up to 1km. Where they should differ is the amount of damage, and if AP is used, the damage curve in relation to distance. If AP is used, then we have something called kinetic damage, which really should be a damage curve drawn over distance. Machine guns can and should be considered kinetic weapons; 20mm and 30mm autocannons that fire solid all metal shots of tungsten, each shaped like a sabot, would be considered kinetic.
Your armor will have to be differentiated as a composition, or a choice of three times --- Anti Kinetic (face hardened); ERA or Explosive Reactive against HEAT; and Ablative, where the armor literally burns into smoke, completely stopping lasers and energy weapons. If this was a game, I won't be offering an all Anti-AP, or All anti-HEAT, or all Anti-Energy. Instead, offer a variety of armors that offer different levels of damage reductions for each. Armor A can have 10% AP, 20% HEAT and 30% Energy, Armor B can have 15% AP, 15% HEAT and 15% Energy, for example. In effect, these are modular armors with differing damage resistances or "quirks".
If mechs with anti-aircraft capability, using missiles and kinetic weapons, they can reach up to 10km away, which is the range common with modern day CIWS like the Phalanx. Such mechs provide a protective bubble over the rest of the mech force --- and their effectiveness becomes the reason why aircraft and helicopters have become rare over the battlefield. If you go back to Macross, the original designs that would become the Warhammer and the Rifleman were in fact, anti-aircraft mechs.
