Tactical Assault Group (TAG) / Offshore Assault Team (OAT)TAG are Australia's primary CT unit.
As B Squadron of the SASR, members undergo the same selection
and training as members of the "regular" SASR. TAG's training facilities include
advanced outdoor close quarters battle ranges, an urban CT complex, aircraft
mock-ups, and sniper range.

An off-shoot of the TAG group is OAT, or the Offshore Assault Team. Initially,
twenty divers from the Royal Australian Navy Clearance Diving Teams switched
branches to the SASR to help man the new unit. OAT, as the name suggests,
specializes in maritime assaults; including ships, ferries, and oil rigs. OAT is
considered a separate but equal element of TAG.

TAG/OAT operators utilise a large arsenal of weapons in their battle against
terrorism. The standard assault rifles are the M-16A2 and F-88 5.56mm rifles
(the F-88 is a localy fabricated Steyr). Pistols include the Browning HP 9mm
and the SIG Sauer P-228. Although the entire family of MP-5s is used, the
favorite is the MP-5K. The Beretta RS 202 shotgun is used, and no less
than four different types of sniper rifles are in their inventory; the 7.62 Galil,
HK PSG-1, Parker Hale 82, and the Finnish Tikka .223.

TAG/OAT operators are HALO/HAHO qualified, and are proficient at heliborne
insertions as well. Cross-training with other countries is not uncommon;
Australian officers are permanently assigned to both Fort Bragg (home of
Delta force) and Little Creek, NAB, home of Navy SEAL counter-terrorist
activities.
