I see no reason why the Rooikat 105 should be 9.7 when the arguably better Rooikat MTTD sits at 9.3 with an autoloader with the trade off of 1 less crew member and no smokes.
A manually loaded cannon with a 2 second longer reload and a higher BR is nowhere near a fair trade for a few smokes and an extra crew member…
the wiki page for the MTTD is also outdated and states that it lacks the DM33 round that was supposed to justify the higher BR of the Rooikat 105 in the first place:
“While it lacks the most powerful DM33 round of the Rooikat 105, the ammunition options are still generally sufficient for the opponents the MTTD will face”
