Honestly, Commandos are no different from any infantry. The only
difference is that Commandos are basically Airborne Infantry.
Guards are also Infantry, but they fall under the Cavalry as they
are a highly mobile unit using vehicular transport, such as light
armor and helicopters.
So come to think of it, CDO, Guards, AI and the normal Infantry,
are all INFANTRY. Only difference is the difference ops. scope and
the different training they receive. But mostly are still trained
as Infantry before being trained in the special skills which sets
them apart from each other.
