I like the vg 1-5

r4m have 0.4kg of explosives. Their blast radius should be 25-35% of that of a hand grenade. Honestly - that’s not much.
Besides, you can’t do any damage to the tank, but you can with Tempest bombs.

Let me dream of having a proper gun CAs damn it

I dream of flying a Me262 in Normandy and will ask for it, but I understand the balance and not trying to bring 24 CAS missiles into the game. I understand that they should only kill with a near direct hit, no worries.
The M8 rocket weighs 18kg, the R4M weighs 4kg, there’s a 3-4x difference in explosives too. So take the damage of the M8, reduce by 3.5-4 times and you get the damage of the R4M. It doesn’t seem to me to be OP.
