1. The Army is trying to discipline the way it force generates soldiers for overseas deployment. The way this is accomplished is through a system known as the managed readiness system (MRS). The Army believes it can sustain 2 x task forces (TF) of 1000 soldiers. This is referred to in the MRS as the two lines of operations. The first line of operation contains odd numbered TF (1-06, 3-06, 1-07, 3-07, etc) are currently earmarked for deployment to Afghanistan. The second line of operation contains even numbered TF (2-06, 4-06, etc) and have not been committed to a second theatre of operation. Included in managed readiness is an operational reserve of Bn strength.
2. Yes and no. Reserves have always made an important contribution to international deployment (Medak consisted of 2 PPCLI with a very large component of reserves). For a TF to be ready for deployment within 30 days they need to be trained and ready to go. Unfortunately, without a mission...they may be waiting for awhile. Having said that, things can change very very quickly on the domestic political side and on the international scene (we are focussed on Afghanistan, Sudan and Haiti but what about other places around the world? ie Zimbabwe).
