Against brits as PE I would try going T3 before T4 and get out an AC and start inflicting mass damage on those tommy squads. If you play right and have good map control you can easily get out an ATHT before his Stewart hits the field. It's always better to get vehicles to fight tommy squads than panzergrens because you're not taking any casualties and you can just repair the vehicle if it gets damaged. That means you have more manpower to spend as well as reducing the amount of veterancy lts get. If you're struggling against the British blob then I would also suggest saving up for a few goliaths. Those things can immediately make the brit player call gg if you get it right.
