I kept the comms gear small because Squats are more technically advanced than the imperium so their tech would not need to be as big . Also, this is battlefield comms... not interstellar comms so I wanted to keep it small. If you want to say it's "too small" for grim-dark, where is the T'au comms gear? One little antenna sticking out of a helmet .

It was always the plan to convert extra comms troopers from standard infantry... and I needed four to cover my army so I converted an extra three .
