- Give reworked HQ glider to Commando doctrine and remove it from Vanguard.
- Add Assault Sections to Vanguard.
Adding Assault Sections to Vanguard would be more risky than the current repurposed glider HQ. As the popularity of Ostheer's Mechanized Assault and Strategic Reserves suggests, 0CP call-in CQC infantry pressure (into follow up light vehicles) into a heavy tank is an effective and reliable strategy. At least Commandos in Vanguard are not a primary reason to pick the doctrine for in most cases as Commandos are expensive and come at a time where you usually need to invest in AT or tech.
Adding Assault Sections to this doctrine would likely make it become the go-to pick for any map that is close to mid range orientated. It's a mid-late game doctrine and I think adding a strong early game to that would be way more dangerous than the glider.
Otherwise you could just replace flamethrowers on Mobile Assault.
I don't think that would be a net improvement for Mobile Assault. The doctrine already has a CQC squad (though ambush-themed) and RET flamers are good in their own right.
I expect flamers will become even more valuable (on all maps) now that it's going to be possible to combine them with the smoke barrage as a means to clear HMGs out of garrisons for relatively low effort.
First of all merge M5 and M10 in the Lend-Lease doctrine and call it Lend-Lease Armour as suggested before.
That's not possible. The M5 was made a call-in specifically because it couldn't be put into Brit tech anywhere comfortably. Platoon tech made it come too early and AEC/Bofors tech made it too expensive / come too late. Can't merge a call-in ability with the buildable M10 as the UI doesn't properly support that.
Then put P47 loiter in the doctrine so it becomes viable in late-game.
I was thinking of potentially swapping Crew Repairs for a Combined Arms type of assault ability that would add some late game power to the doctrine but comes with some requirements to use to its full potential, instead of adding another no-brainer click-and-forget ability (skill planes). Designate Command Vehicle ability could work too.
