Ansible uses the become, become_user, and become_method directives to achieve privilege escalation. You can apply them to an entire play or playbook, set them in an included playbook, or set them for a particular task.

- name: checkout repo
  git: repo=https://github.com/some/repo.git version=master dest={{ dst }}
  become: yes
  become_user: some_user

You can set the become options per:

playbook
role
task


Per playbook:
- hosts: whatever
  become: yes
  become_user: my_username
  roles:
    - checkout_sources
    - install_dependencies
    - make_dirs


Per role:
- hosts: whatever
  roles:
    - checkout_sources
    - role: install_dependencies
      become: yes
      become_user: my_username
    - make_dirs


Per task:
- shell: do something
  become: yes
  become_user: my_username


You can combine this however you like. The playbook can run as user A, a role as user B and finally a task inside the role as user C.
