There's also what looks vaguely like a red bird in the upper left corner.
Oh, and hello. Been lurking since Decade.
I mean... you know, realistically speaking, the JSDF or UN should've long since rolled in with tanks and ludicrous high-power weaponry by now. The Security Council should be taking a vote on whether or not it's acceptable to nuke Japan in order to end the Greed menace. That won't happen because OOO just isn't that sort of show.
Setting tone and sticking to it is a part of storytelling and stories just aren't obligated to use a realistic tone. OOO is whimsical and doesn't want to be taken too seriously and that's not going to change anytime soon. If this was a quasi-realistic show like Kuuga or Nexus, then you'd see the Kougami troopers winning more fights... but they'd also probably have main character status.
