Information warfare has not really been a thing yet with just T1 units. Some sure have cloaking and can snoop around for a bit, but there is nothing to mask the presence of your units from enemy long range sensors with. T2 Stealth Field Generators will allow commanders to turn the tables big time, potentially hiding an entire field base with just one of them. With the advent of T2 Radar Towers and a host of medium to long ranged ordnance, an ability like this should find a lot of use. Anyhow, energy cost of continuously running multiple of these devices will most likely necessitate use of T2 Power Generators.
