The British Army North Irish Horse box looks like a strong British starting point.
However, it is not only a Churchill bundle. Instead, it gives new Flames of War players several usable directions. For budget players, that flexibility matters a lot. This is a summary of a community post found here.
British Army Churchills, Shermans, and Rifles All Grow From One Box

The army deal includes an A5 rulebook, four Churchill 75mm tanks, and two Churchill CS 95mm tanks. It also adds three Sherman 75mm tanks, one Firefly, two M10 17-pounders, and three Staghound armoured cars. Better yet, the set includes decals, unit cards, North Irish Horse tokens, objectives, and a Forces of War unlock code. That means a new player saves money before buying any add-ons. The article then uses the Italy book to build three 100-point options around the box. The obvious route is the Italy Churchill Armoured Squadron. This formation uses an HQ, Churchill troops, optional Sherman support, and Stuart recce. In the sample force, five units hold the formation break.
Nine Churchills with FA9, SA8, and TA2 drive forward to bully objectives. Meanwhile, Churchill CS tanks add an artillery template. Shermans, a Firefly, and M10s provide serious AT14 firepower. Staghounds and Stuarts add Spearhead when missions allow it. Hurricanes add another template and rocket attacks against top armour.

At $206, this looks like the cleanest armored entry.

The second route is an Italy Sherman Armoured Squadron. It has only four formation units, but the anti-tank profile is sharper. HQ Shermans provide artillery, while eight 76mm Shermans bring AT12. Also, three Fireflies add AT15 punch into heavier armor. Staghounds still handle Spearhead, while an Italy Motor Platoon supports objectives and assaults. T

his version costs $261 and feels more mobile, but less brick-like.

Finally, the article builds an Italy Rifle Company. It uses two infantry platoons, mortars, 6pdrs, carriers, and tank support. The infantry can defend or work beside Churchills and Crocodiles. Meanwhile, mortars add a template, and 6pdrs provide AT11 protection. Staghounds help assault troops deploy forward through Spearhead opportunities. Shermans then handle light and medium armor while the assault package closes.

At $201.50, this is the cheapest and most balanced option. Also, it clearly suits players who like the Maneuver stance.
Summary and Final Thoughts
Overall, this army deal does a lot with one starter box. The Churchill list hits hardest, while Shermans bring better anti-tank reach. However, the Rifle Company may suit players who want attack and defense flexibility. It is a practical article because it connects purchases directly to playable lists
