Infiltrators are the cheapest Squad available to the Empire.
Their ability to deploy anywhere on the table is a nice advantage in many situations. Their Pistols are not powerful, but can still put out damage as needed.
Confuse is a situational action, but can be very powerful in the right context. For example, you could make an enemy discard a hard-won Reinforcement Token, replacing it with a Shaken Token... making them more likely to fall in the future.
