Ability to call the soap web service from the browser

I need to clarify some issues regarding soapy web services.

1) can I call the soap web service just by typing the endpoint url in the browser?

2) Does the answer answer the question of what technologies are used to develop a soap web service?

If I need to call a soap website service, I need to submit a soap request. But simply sending a get or post request from the browser cannot generate a soap request. so by default I shouldn't be able to call the soapy web service with just the browser.

but the following two resources contradict the above assumptions. Can someone explain to me how these soapy web services can be called without asking for soap?
