If I recall correctly, in my last XCF campaign, enforcers were used as heavy support. Short summary of advantages for me:
Strength to carry heavy weapons, such as the Sniper Gauss
Unable to get wounded, only loss of HP, IIRC.
No downtime if injured.
Immunity to PSI actions
You get weight reduction with power suit, power armor and juggernaut armor. All of these allow regular agents to carry heavy gauss weapons. The only late-game armor which does not is stormtrooper armor. So, by the point you get enforcer, your agents should already be able to carry gauss without problems (at least if you prioritized capturing heavy MIBs for their armors). Also, after the somewhat recent addition of advanced sick bay, agent downtime due to injury or sanity loss is less and less relevant.
So, not really sure of the actual use case for these now (in the sense how are these better than, for example, spartans or even some other transformed soldiers).
Maybe this should be pulled to a separate thread..
