Although the Phase-II Clone Trooper Armor always got a lot of love…The Phase-I Clone Trooper Armor was always the best design to me due to the Phase-I Armor's likeness to Jango Fett's Mandalorian Armor.
From the Phase-I Clone Trooper Armor. To the Phase-I Clone Commando Katarn-Class Armor. And especially the Phase-I ARC Trooper Armor with its numerous Mandalorian influences (Helmet mounted Rangefinder, Kama, Jetpacks, Wrist Rockets, etc.)
Phase-I Armor for the Win...!
This is Concept Art for The Mandalorian (Din Djarin) Helmet's T-Visor HUD (Heads-Up Display). It was shown in The Art of Star Wars: The Mandalorian book. Unfortunately, Din's helmet Heads-Up Display wasn't showcased in the 1st episode of The Mandalorian. Instead, the show had Din use the scope of his Amban Phase-Pulse Blaster (AKA Amban Sniper Rifle) to scan the hideout of the Nikto mercs that were keeping Grogu.
The series has presented some very cool features of Din's Mandalorian helmet. Like when Din eavesdropped on Imperial Officer "The Client" & Clone Engineer Dr. Pershing by: A) Scomp-linking his helmet to his scope to enhance its vison mode, allowing Din to lock in on their position inside their Imperial safehouse and: B) Adjusting the scopes controls to listen in on the Client & the Doctor's conversation concerning Grogu's fate.
Since Mandalorian Helmet T-Visors are known to possess many features (Heads-Up Display, Macrobinocular Viewplate, Enhanced Vision) I hope we'll see something close or similar to the afore mentioned T-Visor concept art pic being utilized by Din Djarin & other Mandalorians. Because frankly, with all of the other Mandos that appeared in The Mandalorian, it was odd that, except for a few rare occasions, any of them ever used their T-Visor's Heads-Up Displays to target an enemy, scan an area for hostiles, etc. (And if someone did use their Helmet's HUD, it would just look like a plain video camera shot instead of a view similar to the T-Visor concept art pic shown below.)
Hopefully we'll get to see a Mando use their helmet HUD's featuring a T-Visor POV (with accompanying data read-out graphics) someday on-screen. Maybe even in the upcoming The Mandalorian & Grogu film.
