I suppose that in that case I must chime in. I'm not too impressed with enforcers, if you compare them to other (human) units wearing an adequate armor and with spartanism transformation. Spartans are much better at least in many respects (but I suppose there are some niches where enforcers could be useful; one minor niche is the complete resistance to PSI damage type, but at the point you get enforcers that is no longer really relevant).
Also, it can be dangerous to use at least some 1x1 AI units, because even a single laser or plasma shot could roast the unit to the cinders, i.e. also destroy the AI unit so that it cannot be restored. Thus you may need to be careful with these. I'm not sure if I've seen this with 2x2 units, though their bodies could be wiped out as well with explosions at least. I've seen a flying drone completely wiped out by an enemy laser or similar a couple of times, but not sure if this could happen with enforcers.
