This module can be used early in game, or somewhat later depending on the strategy you are using. When assembling a fighter rush, the engineering module is a must. It’s also a useful (and required) line of research when removing crystals from RU patches. The rammer and mimics are quite effective when trying to eliminate the threat of a popping crystal in the presence of workers.
Support Modules usually take the first spot, but often an early game mimic rush may push Support modules back to the 2nd spot and Holographic Emitters is researched first (it only takes 60 seconds). In the fighter rush... the rammer often takes 2nd spot behind support systems to clear the crystal from the RU patch.
Once your crystal is cleared, why not move his a little closer
You can also rush for crystal processing by researching SALVAGE first, this however is not a good idea unless you have plenty of team cover to watch your workers. Crystals are risky business and backfire too easily for my liking therefore I rarely salvage them.
