[X] "Home-on-Jam" Extended Range Precision Guided Mortar Bomb: If that jammer is broadcasting loud enough to wash out communications like that, it's loud enough to give away it's location. Design a new mortar bomb compatible with existing stocks of the Jaguar mobile mortar system for ease of rapid deployment by Intruder and other ringleaders, rather than having to set up a new production line for the launchers as well. It should be capable of homing in on the radio emissions of the jammer via adjustable fold-out tail and body fins deployed after launch that allow it to perform significant adjustments in trajectory. If you're going through the effort of putting the extra fins into it anyway might as well make them able to provide enough lift to extend the bomb's maximum range too, so Intruder can just keep a few Jaguars back by her side where the jamming is weaker and they won't interfere with her plays, and still have them able to engage even if she is a handful of kilometers away. Include some way for the ringleaders to adjust what frequencies it should or shouldn't be targeting in the field, so that they don't have to come all the way back to you if Griffin alters how the jammers broadcast to try and prevent targeting, or if there's a friendly emission source in the field that they don't want to hit. Fitting the fold-out fins and guidance system into something the size of the Jaguar's mortar bomb is going to reduce the amount of volume left for the warhead, so see if the new stronger high explosive you put together for Destroyer's grenades can be used to offset that.
[X] Laser communication relay system. The signal reciever is gear made to be carried or mounted on Sangvis Dolls that can recieve laser-based data transmission. The signal sender could be ground-bound or airborne (maybe mounted on a UAV). Laser communications require line-of-sight but are unjammable.
[x] UAV-mounted signal boosters. ''So, what about... UAV-mounted signal boosters ? They could be like... talkie-walkie or assistants to help getting your messages... directions to your... stage crew ? Bleh, enough with theater stuff, what I mean is that a small squad of 3 or 4 UAV with signal boosting equipments could help you get your signal through jamming by either moving closer to your troops easier then you or providing different signal vectors to avoid directional jamming signals !
[X] Radio Inferometry - many troops → many radios → distributed radio array → "big" radio telescope → better resolution → easier to "point" at Intruder & hear signal. Reverse polarity to transmit back.
[X] Modulate our own jammers - encrypted data looks like static; as long as we're using our own bigass radios, might as well use them to shout commands too
[X] Laser Semaphore - Heck, laser comms don't even need to be line-of-sight. Point a bright enough laser at a wall, and your troops will be able to get data just from seeing the scattered light. (bright enough, and that light can bounce many times, reaching all sorts of places)
[X] Makeshift ansible - I remember something in the game's lore about weapon-linked dolls always knowing the location of their gun? Keep the gun, and vibrate/move it (shake it baby shake it) to send data.
[x] Medium-sized heavily armored dinergate-based armadillo bot. Rolls forward, ignoring fire. Spools off cable to connect to Invader or paired receiver ardillogate. Emplaces itself and acts as retransmitter. Attacks by rolling into T-Dolls and grinding on them. Has laser comms receivers.
[x]Spreadspectrum chirp transmission. It is entirely possible to have our radio send highly compressed data packets over a wide range of frequency. This hard to counter because the only foolproof countermeasure is that the enemy transmiter is more powerful than yours.
[x] Communication missile. Repurpose some old wire-guided anti-tank missile if you need to. Five kilometers of fiberoptic cable, retransmitter with fifteen minutes of battery power or power wire to go with fiberoptic, cheap enough to spam and not worry if stuff breaks, powerful enough to overwhelm jamming locally. Because, frankly, lasers are useless if G&K start spamming smoke.
[X] But for lasers... You know, first communication satellite was literally reflective balloon? So fill the sky with mirrors! Mylar film, hexamine fuel tablet, completely passive reflective hot air balloons, could be spammed by thousands, communications firmware will need some updates to deal with reflections, but it's a dumber than a brick solution. Frankly, implement anyway and program drones to deploy floating reflectors and direct communication lasers at them in case of jamming. Let hostile T-Dolls deal with, heh, smoke and mirrors, even if actual communication method would be completely different. Weather-dependent, but that's why both Intruder and drones will get some balloon deployment modules.
[X] Human armies deal with such command issues by having autonomous command element at lowest level of combat force. Design either Sergeant-class Doll or Non-Com bolt-on package, that will provide limited command and control response if Ringleader is indisposed. No need to make them very smart, just a bunch of situation-dependent packaged battle plans would do to deal with completely predictable flanking maneuvers and loss of communication.
[X] Turn to the documentation of old Soviet equipment. Everything new is the same old thing, right? Just transfer it all to a new platform and put our sign on and we're done. Isn't that what they called Katyusha artillery? Earth should burn from your missiles!
-[X] Also, you literally just recently provided Destroyer something that might help you with this task. You just need to tweak the idea a bit with a file.
-[X] Install Dinergate tape recorders capable of playing old Soviet songs to further demoralize the enemy. Everyone should know that YOU are the real USSR receiver, not these budget fakes! And it might also allow you to clog up your opponents' airwaves to degrade their communications. Double benefit!
[X] Message runners - the oldest communication tech? It worked for ancient humans. Probably want to use multiple in parallel to provide redundancy against the inevitable suppression fire.
[X] Lead from the front - Intruder likes to sit waaay back to provide cover fire and direction, but what if she didn't do that? Hole up somewhere secure or hidden (but close) and strike via arcing shots. (Plus the Drama! She was here all along!)
[X] The identical hordes - all the decoys. All of them. Every bot gets remodeled/makeover'd to look like Intruder. Even the Dinnergates get cute little dresses
[X] Laser communication relay system. A signal of laser signal senders and relievers.
-[X] Backpack or head mounted relay gear for the Dolls.
-[X] UAV mounted relay gear. Either adapted for use on existing drones, or built into a custom drone.
[X] Signal amplifier.
-[X] A monstrously powerful radio signal emitter built to overpower jammers at close range. Mounted on a wheeled or legged chassis.
-[X] Equipped with anti-drone defenses, either laser based or ballistic
[X] Polarised communications equipment.
-[X] Custom versions of existing comm equipment to introduce radio polarisation, filtering out unwanted radio signals
[X] Subvert G&K dolls - as far as I can tell, most G&K dolls are motivated primarily by ice cream and friendship. We can do those! We're already working on hacking, but let's try some more overt options - throw up some billboards "Join Sangvis Ferri! 32 flavors of ice cream! Extra sprinkles for every friend you refer to our side!". (Watch out for fake defectors, though)
[x] Field telephone. You can't jam field telephone. You can't track field telephone by electromagnetic emissions. You need to lay field telephone on offensive. That's specialized dinergate with a spool of wire. You need to retransmit signal from field telephone to existing command and control channels. That's either second, differently specialized dinergate with a large radio or special addon to existing dolls. Retransmitter is most vulnerable part of whole process, because it radiates loudly, so there need to be spares. Whole solution bolts on to existing drone forces. Of course, it should not radiate or be noticeable before jamming makes current command and control solutions untenable, to prevent early location and destruction.
[x] Some Large Loudspeakers. All our dolls come with rather high-resolution microphones, that they often don't know what to do with. And ability to encode digital data in the audio stream is rather old. It's one-way communication, but large speaker system that transmit correctly encoded and signed order packages in modem sounds is better than nothing. Big fold-up panel of ultrasound tweezers to make a steerable beam, amplitude or frequency modulation, and you have your medium-range remote control that G&K won't know what to do with or even know it's happening unless sound beam hits them head on. It needs emitter roughly the size of a panel truck's side, and if you have that, you can cram some other goodies in said panel truck. P.S. What's resonance frequency of a T-Doll? Need to check if this can induce component failure on direct hit.
[X] Frequency-hopping spread spectrum. With cryptographic algorithm to control frequency change it is effectively impossible to predict the next frequency (as long as the key is secure and regularly updated), forcing the enemy to either use wideband jamming, reducing effective jamming power over any specific frequency, or trying to locate each new frequency as it appears, which can be further complicated via shortening the duration spent on every frequency. In cases of heavy jamming, you can make all available units other than the primary transmitter to send garbage on additional frequencies, either forcing the enemy to, again, go for wideband jamming, reduce wattage on each individual band, or even to miss some of them. After all, the enemy is going to have only so many dedicated jammers, presumable less of them than you have radios.
[X] Meta: General Upgrades - Any communication upgrades we devise for Intruder will likely be applicable across all Sangvis Ferri forces. Don't forget to apply them everywhere we can.
[x] Chirp spread spectrum. A technique lifted directly from a wikipedia article that permits to send very short but powerful radio Pulses over the entirety of the spectrum the transmitter as access to.
[X] Simplified command set - A simpler signal is easier to discern than a complex one. Sacrifice bandwidth for connectivity. Set up a Brevity Code system so that, when jammed, Intruder can "shout" commands like '2-2-1, 5-3-14, 1-1-7-1-16-5-17-16' (Squad 2, provide covering fire for squad 1. Squad 3(heavies), destroy the enemy's cover. Squad 1, enter the building to the north and destroy the jammer in that building). Maybe even provide a more simple/rugged transmitter (band-gap radio?) optimized specifically for these transmissions. (maybe even just transmit basic text - Agent mentioned receiving "targeting data over the network", so regular comms sound like they include a lot of bonus data)
