CAV 2.M Electronic Warfare Revision

Following discussion with a couple of CAV players with experience in real-world electronic warfare, I've elected to attempt a more drastic rewrite of the electronics rules for CAV 2.M. The existing system has three main problems. The first is that generally speaking, if both sides are fielding electronics support models they simply cancel each other out until one is eliminated. The second, and most problematic from a gameplay perspective, is that electronics support operates in a small radius around the ESM model. This promotes huddled formations which block line of sight to the supporting model, making it very difficult to attack. The third issue is that the game mechanics for defensive electronic warfare don't correlate well with known technologies. While CAV is a science fiction setting, it is generally preferable in science fiction and fantasy to retain some connections to reality; this makes readers or players more willing to accept it when you do wave your hands and say "magic" or "science".

The first of these issues I attempted to address in the initial draft of 2.M, by introducing greater variation in the numerical bonuses granted by assorted ESM models. However, the impact was minor, and the other problems remained unaddressed. So, I started talking it over with a few other long-time CAV players and we came up with a number of possible changes.
1) Target Lock requires Line of Sight. This simple change has all sorts of interesting implications. ESM models can no longer hide behind heavily-armored CAVs twice their size and still provide targeting bonuses, and fire support models must rely much more heavily on CFP-equipped Recon models if they want targeting assistance.
2) Non-AoE Electronics. Change the electronics SAs so they grant a bonus to X section-mates rather than all models in a given radius. This eliminates the huddle and in combination with (1) further encourages use of Recon models for actual reconnaissance roles. A range limitation could optionally be applied for sharing of bonuses, forcing sections to retain some kind of cohesion, though this would work at cross purposes to the enhanced role of Recon models.
3) Revise ECM entirely. With little connection to reality, and poor balancing relative to EST, ECM as written was just asking to be removed. Instead, we came up with the following three options. First, a model can perform "defensive jamming", making itself harder to lock onto. This functions identically to the old Jamming, giving a bonus equal to the model's EDV. The ECM ability is replaced with Electronic Defense Coordination (EDC), an ability which functions similarly but uses the affected model's EDV rather than sharing that of the EDC model. Many models would be given EDV 2 to make more effective use of this ability, which is weaker than the old ECM but more balanced against EST given its longer duration. Finally, there would be a new Jammer ability, granted to certain Recon and ESM models, which allows them to scramble the targeting of nearby enemy models, inflicting a RAV penalty. This option would apply a larger penalty than defensive jamming, but the necessary proximity makes it far riskier as well.

These changes still need testing to see if they will work as intended, but I believe they should result in a far more balanced and nuanced approach to electronic warfare.
