To put it bluntly, British and French doctrine are far too different to eachother and the Americans.
Now, there was suggestions to pretty much to revert the buffs of the Pan-Asian doctrine (more hp for slower units). However, the Allied doctrine (which might as well be called American) already has dibs on speed nerf, so I guess I have to make some of my own suggestions.
Commonwealth Doctrine (Rearmament)
General Strength: Construction cost -10%, construction time -15%
This is to reflect Britain's effective repairs during the Battle of Britain, where despite the constant bombing of factories and air strips, the British were still able to restore most of the building's functions.
General Weakness: Production time +15%
Britain's mobilization came rather late. They really didn't go partial war economy until the Munich conference. And unlike the USA, where it can easily pump tanks and soldiers in mass quantity (which reflects the Allies Doctrine), Britain has neither the resources nor the manpower to sufficiently defeat Germany by itself.
Note, several of the following suggestions can be discarded in the final product.
So on to the units:
Militia - 25% urban terrain buff,
The militias of Britain were the Home Guard, where it is expected urban fighting will happen. The buff will also compliment Churchill's quote: "...We shall fight in the fields and in the streets, we shall fight in the hills..."
Infantry - 1/2 day research
Pretty much what I said on the general weakness. Also didn't help that British non-motorized infantry didn't fare well in early war France, eventually leading to the Dunkirk evacuation.
Motorized Infantry - Health +10%
I based this on the fact on the British army during the North African campaign, where it was very motorized. From Operation Compass to Crusader to El Alamein, the British army could afford to have trucks, whereas the Axis army simply lacked the oil for even the Italian navy to ship oil across the Mediterranean.
Commandos - Same buffs as the Allies doctrine
The price is much more expensive, but they are faster.
Paratroopers - Production cost -20%, -1 day research
As the pioneers of paratrooping, including operation Biting and Market Garden, it would be disservice if I don't include this.
Anti-Tank Artillery - 2 day research
After Dunkirk, Britain has the choice of producing their 6 pounder guns, which was on par of the PAK 38, or choose the smaller and cheaper 2 pounder. Needless to say, they chose quantity over quality.
Anti-Air Artillery - 10% damage vs Air
Battle of Britain.
All of the Self-propelled ordnance - 1/2 day research
I can barely find any British development on this category.
Interceptors - -25% production cost, 10% damage
So pretty much Britain's fighter production is to produce as much fighters ASAP. The fact that they were so desperate and low on steel, that they constructed the Hurricane and the Mosquito out of wood, exemplifies this buff (even if an Axis fighter still has more health).
Naval Bombers - -1/-2 day research
Destroyers - damage 10% to surface fleet, damage 15% to submarine
Britain, much like USA, has an emphasis on fighting submarine. British escorts were effective until USA swarmed the Atlantic with lend-lease, straining the escort vessels.
As for the Secret units, it can copy the Americans.
