Enforcers

Enforcers(also called Space Policemen, skiny marines. ManMarines, IronManMarines, ) are mantic equivalent to Spessh Mareeeens, more specifically to Ultramarines, though their models do look quite different, and their background, while following similar archetipes has began to develeop very differently speacially since deadzone provided us with more info about them.

Overall, enforcers are the GCPS elite army, but they are not really deployed en masse but rather used as a special ops squad, with a lot of focus on secrecy and lightning attacks, which would in many ways make them the polar opposite to certain space marine armies, while making them very similar to a certain non existent legion(to the point were every enforcer that is not a ranking officer is forbidden from revealing his face).

More comparison to Space Marines

Ok, so what makes the enforcers be more than just poor mans space marines? Well first of all while both serve a cuasi totalitarion regime, enforcers have much less autonomy than space marines, since enforcers are said to be under the direct rule of the council of seven, with little to no free will when it comes to deciding when and were to deploy.

Also lorewise, while the space marines are organizaed into chapters, each a fairly individual self contained army, enforcers are instead considered a single fighting force and mostly using the same colour scheme, with the exception of some characters.

In essence, whereas space marines are a collection of knightly orders each mostly individual, enforcers are a single really big army, that mostly suppresses individual identity in favour of the army's uniformity.

Amazingly though, while the enforcers tend to supress individuality within their ranks, their soldiers, tend to have somewhat a story before joining the army. With many of them having even been dreadball players.

Another key difference between enforcers and space marines comes in the shape of mortality, enforcers are not only much more prone to dying than space marines, but also age, which means some have to retire, the dossiers says that when they do they go to a pleasure world(either that or they are sacrificed and uses as material, whatever sounds more confortable)

In the end Space Marines are genetically enhanced humans that fight for the glory of the emperor, enforcers are soldiers that fight for the council of the 7 in order to gain money and a retirement package, Quite a big difference in my opinion
