Would these units still trigger Les Terribles

No it wouldn't work, 5th rangers is an example of why it wouldn't work.
Card is plenty strong anyways free turn 5 0 op 6/6 in the frontline
Should probably have an infantry requirement, otherwise it's just busted, in US/Ger frontline it can essentially pay for itself immediately if you have a panzer 1a

What about setting it -2 operation cost
elfin hemlock
I mean you aren't playing this unit for its stats I would probably make it cost one more give it +1 health, and restrict it to only infantry
That way it makes the time to get blown out by big american infantry longer, and it kinda synergizes more with the high op cost deck, because you do actually want some units to have op costs.
It could even say other friendly infantry, and then the op cost of itself could be increased to 3 making it kinda like les terribles
but maybe thats unwise

frontline is already low op and infantry focused anyway so i dont think that restriction would help

turn 4 8/8 4th ranger in the frontline
elfin hemlock
frontline is already low op so you see nothing wrong with a card that is basically a strictly better grief? I don't see how that's not a problem.
even if you play it on low cost cards if they're tanks with blitz it's basically cheating out at minimum 3 kredits per tank
turn 2 that, turn 3 you could blitz if you wanted 3 1/3 tanks to the frontline and hit face. Turn 4 blitzkrieg they die.
