So I'm just thinking - I've never seen anyone actually USE Rutheless Strategists and I'm wondering if it could actually be a thing.
For reference in case you don't have it in front of you.

The idea here, is that I don't generally LIKE to bring a lot of squadrons into my lists because for me, Armada is about the huge ships, and not about the fighters. So my dream is to have a ship-based solution that can shut down squadrons. I USED to simply destroy all their ships and count 400 points for victory - but with Flotillas that is now much harder to reliably do.
So first off, you need a ship that can take it, and you need some squadrons of your own that can engage other squadrons, and also have hull available for taking damage. At first glance I thought of a swarm of TIE Fighters, because you can get a TON of them, but with only 3 hull for 8 points each, I wondered if I couldn't find a better option. I looked to the rebels and found some better options, namely the Y-Wing or the YT-1300. But there are pros and cons for trying to incorporate ruthless strategists on either side. I'll talk rebels first.
Rebels:
Y-Wing is probably the best option overall, because they are moderately fast, and have a lot of health, and they can also do some serious damage AFTER you defeat your opponent's squadrons. YT-1300s are also an interesting option because they have even more hull, (granted they are also more expensive), but also have blue dice - and that is important because of Toryn Far.
You see, if you are going to be using your ships for Anti-Squadron attacks, you are very likely going to be throwing a ton of blue dice at your opponent's squadrons. Having a Toryn Far in the middle of your fleet gives your blue dice a MUCH better chance of hitting. And Toryn will also help your YT-1300s attack enemy squadrons, enemy ships, AND counter attacks - so triple bang for your buck, while the Y-Wings roll black dice against ships, so you'd need to further upgrade your fleet with a bomber command center. If you went with YT-1300s you wouldn't need a GR-75 at all if you didn't want it... and even if you did you wouldn't be restricted to Bomber Command.
In terms of ships - I think the Assault Frigate MkIIA is your friend here. Two blue dice for Anti Squadron, and blue dice on every arc will synergize well with having Toryn Farr nearby. It can help you get that accuracy if you are shooting a squadron with scatter - (Or you can give it H9 Turbolasers as well). I think the key is to have at least TWO ships with Ruthless Strategists and H9s though, because if you've only got one heavy-hitting anti squadron ship, your opponent can simply try to avoid it and really limit you.
Imperials:
A TIE swarm can certainly fit a ton of squadrons on the table, and while they only have 3 hull each, they also have the advantage of being able to be virtually Everywhere - so it's very likely that when you are shooting at your opponent's Jan Ors, Luke Skywalker, or Mauler Mithel, that you will have at least 1 or 2 TIEs engaged with them, offering plenty of options for Rutheless Strategists. There's also the amazing Mauler Mithel for YOU to use as well, able to synergize by dealing additional unblockable damage to multiple squadrons at once. TIE Bombers are also cheap and have a lot of hull here, but like the Y-Wings, they have heavy so won't be able to lock down ships on their own.
For upgrades I think the Empire has some serious advantages here. Agent Kallus is the first choice for crew - allowing you to possibly roll a red die (or two if you have concentrate fire and REALLY want to kill that Tycho!). Additionally, if Vader is your commander you could also reroll some anti squadron dice at the price of spending defense tokens.... but it's certainly an option if you REALLY need it.
For ships - At least one Victory is a great option here. Tossing on Warlord and H9's will give you 100% chance of hitting unobstructed squadrons on every attack. additionally the raiders can take them, but there is also the Glad II, which has two blue dice without being as expensive as an ISD.
Anyone had any luck with Ruthless Strategists to shut down squadrons? I think it's pretty cheap even if you end up facing a list with only 1 or two squadrons in it.
