The NO-M1-E2904 was developed for use with the NO-M1-1a - Mantus Infantry Power Armor, it became available in YE 29.
Although not specializing in stealth, the power armor has multiple volumetric projectors which are capable of projecting a three dimensional images which are nigh on impossible to distinguish on using visual sensors (for example eyes). The image displayed can be almost anything, as directed by the instructions of the pilot as extrapolated by the computer. This can be used as a direct disguise simply showing what would otherwise be seen.
