Okay, I've just done my research. It appears that the noun "Arme" requires a strong inflection to be applied to the preceding adjective because it's properties are:
1) The noun in this case does not have an article.
2) The noun is in the Accusative case.
3) The noun is plural.
With all of those factors being identified, we add -e to the end of the adjective.
I hope this helps, it took me almost an hour to learn this properly!
My go-to for questions like this is this link: https://www.duolingo.com/skill/de/Colors/tips-and-notes. See the section on Accusative, and the last case of the Plural in the chart.
Das Zeitglockenturm, das alte Wahrzeichen der schweizer Hauptstadt Bern.... why schweizer not schweizen? Can someone help?? My reasoning is Hauptstadt. feminine, singular, schweizer should be weak adjective after definitive article der, genitive case, feminine gender, singular, should have an en ending. Help please!

Having lived in bear country all my life until a few months ago, I have never once heard of a bear having arms. Referring to a bear as having arms would identify you as clueless or not a native speaker of English. Tigers, lions, horses, cats and elephants don't have arms. Neither do bears.
