I have no idea how to justify the price of the french baguettes, I feel nothing but disdain for those two tanks. I died a little every time I saw one of their shells bounce of a halftrack, a HALFTRACK. I suppose it could be useful against a deck that has no armored support but even airborne gets locusts (iirc) and even those are probably a better choice than these "Tanks", at least they would be fast enough to flank. Against 3rd or 15th they are nothing but points better spent elsewhere.
The 35R is slower than churchills (13kph vs 15-18) and has an utterly horrible 4ap3he gun and a single MG. It is in no way maneuverable enough to flank anything and it has neither the armor nor the gun to fight anything other than halftrack head on, this is not worth 55 points. I can only justify it's existence if the opponent forgot both is armor and AT support at home. The 39H is a bit better but only barely, you get a slightly better gun but even less armor (4, this is armored car tier) yet it still can't move faster than the slower medium tanks. The speed makes it unable to flank, still only comes with 1x MG. For this you have to shell out 70! points, just 20 less than the Stuart and I would argue a single stuart is worth two 39H's.
That's not the worst bit, the worst bit is that they have zero sustainability. Stuarts and other fast light tanks can do well with their speed and guns on flanks in the later phases but these are just dead weight, if they somehow survive. I get they're not supposed to be great but there is a difference between "Not great" and trash tier. If you really need anti-inf explosives buy some mortars or even a LeiG, both are better for their costs and less prone to exploding if anything looks at them funny.
If anyone wants to explain how they can be used for their current price I'm happy to learn, but I've removed them from my decks and so have most people it would seem.
