Blurring of faces is a silly thing to do when not needed. SSG is a division strength outfit. Most of the manpower is employed openly as needed.
Covering faces is primarily for the safety of the troops and if any operational needs exist. If troops are being employed in CI roles, then concealing their faces makes sense because insurgents may potentially identify the troops and take measures against individuals or their families. Otherwise it does not matter. Why bother concealing their faces? Many do it to maintain an air of secrecy/opaqueness. In the conventional realm, it does not matter.
