Beats me.
Visually, it looked much better without it. Think the Panther as a
logo, a brand. Less is more. Kinda like when u see a swoosh
element, it reminds you of Nike. Three stripes, Adidas.
When u have a element like the bayonet, it disrupts the general
look and identity. Ppl will say.. "hey that Panther.. looks great..
but that Bayonet.. isn't that similiar to other units?"
All in all, it looked great nevertheless.
