The ARC Trooper Lieutenant is the second rank in ARC Trooper ranks, and can be obtained by completing the Supreme Commander Card Commander Campaign for 
500.
This gear is the standard ARC trooper armor with blue markings. The outfit is most likely based on the ARC Trooper Havoc seen in the Clone Wars television series. An ARC trooper Lieutenant can be seen in the Cargo Hold after completing Mission on Iceberg Three
