Batch painting things in 5s is still working. Another couple of batches got completed again this week.
I am not sure that a unit of just five Assault marines will be too much use, but thats what is in the army collection so thats what I’ve done. Veganman can always try to talk me into painting more if he ever decides to expand the force.
Five Terminators though feels quite hefty enough, especially with three Assault cannons in the unit. Considering that a lot of the normal veteran units have terminators in them as well, I don’t think the force will be low on firepower or power fists.
