Btw joe, are you CDS, COAS or GOC-in-C?
All three, in normal circumstances;
@meghdut is Chief of Air Staff, and acting Chief of Naval Staff; nobody is in charge of integrated Air Defence, or of integrated (not yet implemented, but would have been proposed for 2026 time-frame) Logistics, Communications and Medical Services.
Drawing the attention of the COAirS/actg. CONS to significant developments, opportunities, threats, in a live operations context is a CDS job.
Planning for the actions of ground forces is the COAS job, but it is very unlikely to be an active one in the first 72 hours. At most, there is responsibility for the reconstruction of formations to incorporate obvious areas of strength - mechanisation of infantry, integration of armour and artillery into combined battle teams, integration of helicopters, logistics - and for re-grouping them in geographical points of concentration.
A GOC-in-C role may emerge in the absence of others to take on those roles. Ideally, at least at Army (=multiple Corps) levels, and even at Corps levels, there should be individual roles, but there are no interested people.
C'est la guerre.
Platoon level operations is 3 years, Battalion level operations further 7 years, brigade and division level further 10 to 15 years.
That gives us an idea of how much experience in actual training is needed, for those organisations not involved in actual warfare.
One of the lessons learnt in the current Russo-Ukrainian conflict is this, the amount of practice and training needed. An integrated force is totally useless unless it has trained in an integrated manner, intensively, for protracted periods.
