Armsel Striker page vandalised

[Rockwolf66]

Someone has vandalised the Armsel Striker page and I just spent 30 minutes trying to return the page to it's previous status information wise. I know that I have lost information when I was trying to get the page back to it's previous good status. Could someone please double check the about 50 revisions I had to undo and then could a mod please protect the page as I don't want to do this again.
