There is no need for an ARes Coy Gp to 'deploy nationally' IMHO.
But if you want to build good company groups the tried and true way is to, months in advance (e.g., September), declare that there will be an annual concentration at a suitable training area (e.g., Wainwright, August the following year) with a training aim (e.g., Defensive/Offensive Operations), and prepare for it throughout the training year. Include a 'Gun Camp' during the Spring Break to qualify on your crew served weapons, and do other types of preparatory field firing (e.g., PWT4)
For some reason, this pattern has eroded over time with the effect that all training seems disjointed, last minute, poorly supported, and without any clear final aim, goal or purpose.
But that's just the view from my sanger window...
