I didn't realise they had enough to make an army, AND WERE organized enough to do so, AND create parades and marching bands....
however, our armor is much more complex, and from what it looks like, they are probably mass producing kits for each of their members to have that many troopers with such identical looking armor
our armor is hand-crafted, much tougher to make, and reflects on the fact that a few of us spartans can take out their entire armada of storm troopers
if we can get at least 50 spartans all organized with HIGH-QUALITY hand crafted stuff that is in a standardized patteren, we can match them easily.
What is more impressive, especually today after the constant storm trooper parades, 50 amazing looking spartans with ID numbers, and different helms and colors to reflect the type of spartan (cqb, eva, ect) all marching organized with matching weaps, or an army of storm troopers with identical white, mass production copy armor.
Add to that our female members whom we can dress up as different female AI, and put them in female spartan costumes that make people know they are female somehow, as well as a few vehicles and we will be pwning
