The medic and recce sections sound nice, but weapon sections are no different from currently double bren 5 man sections. I suggest the upgrade come with a transferable bren on the 5th man when reinforced.
I thought of that before and calling it Bren Section Upgrade, as the Bren was as centripetal to the British Army as the Maschinengewehr was to the Germans. However that would serve no purpose other than limiting player choice, while 99% of the time players are going to use 2x Brens anyway, I didn't want to limit the one guy that might want 2 PIAT's.
That said the difference between this section and the current ones is that they give up the option for a marksman / artillery or a medic / healing in order to get 2 weapons, rather than the current of Double Bren Medic Section which practically has it all.
Also, in your proposal, sections will hava 2 weapon slot ? So if any upgrade take up 1 slot, they still can have 1 weapon ?
Yes, Sections have 2 slots and each upgrades takes 1 except for the Weapon Section, which specifically takes none so that 2 weapons can be used. It's like this, their specialization is using heavy weapons, rather than deploying a a marksman or a medic.
About medic upgrade. Either self heal or drop medic crates, both is too much.
I very much want to move away from Medic Sections being mandatory for healing by having healing tied directly to them. I did this by splitting the healing into two parts, their medic will heal the squad, but they may also heal other squads by deploying medical crates. This way, they do not need to be present to heal other troops. I do still think healing is inadequate even with this change, but I opted not to expand on it yet and just lay the groundwork here. The simplest solution would be to allow the British Medics to be buildable at one of your base buildings.
