They are equivalent, but *only* if not given any other arguments (or if given "HEAD", which is obviously the default). HOWEVER! If you give them an argument, they work very differently. So git checkout -f <branchname> git reset --hard <branchname> are fundamentally different operations: the "git checkout -f" thing will *switch* to the named branch (or create a detached HEAD if it's just a random commit SHA1 and not a branchname), while the "git reset --hard" thing will *force* the current branch top commit to the same as for <branchname>. It just so happens that without any branchname they both default to the "current branch", and then the two end up doing the exact same thing, even though conceptually they are very different operations. So they really are fundamentally different, it's just that for the common special case they end up doing the same thing.
