I don’t think that advanced tanks are needed for more efficient and more mobile warfare at that time. Just making an investment into transport for troops and supplies would be enough to hold better at the battle of Marne, or similar situations.
So I would:
explain (with examples) benefits of mobile warfare
explain problems with troops speed and logistics that would cause defeat at the battle of Marne
point towards existing gasoline (possibly off-road tracked) vehicles as a solution
Introducing stormtrooper tactics would be another impactful message.
