Blending into the mindset of the Human Terrain

[Coined]

To be a little more even-handed;

This reads like a "best practices" approach to Small Wars (COIN, low intensity conflict, SASO, pick your buzzword). You are trying to assemble the concepts that have worked in Latin America in the 1930s, Malaysia in the 1950s, Viet Nam in the 1960s-70s, the hords of Middle Eastern expats that are employed by the U.S. Army National Training Centers right now, etc? If so, you've put together a good framework.

Now we find that all the fieldcraft and subtle arts of Small Wars are equally (or more) important than the romantic vision of mechanized brigades rolling through the hills of Germany.

We still have to be ready for full scale combat. It wouldn't be wise to get rid of the hardware. That is not what I meant. Full scale wars like WO1 or WO2 are not likely anymore. Our weaponry and the way the information flows will hamper any possible succes in the latent phase. The approach should be a complementary one in which every soldier is trained in an 3BW environment.
Although we might think that we train for such operations I think we do not.
We stil train at training areas at which we built training villages. In such a TA we train against civilians which are dressed up soldiers, so still we train with our military mindset against role-play with, also, a military mindset.
I don't want to "stove pipe" our training just expanding it.
If you have a look at my fist contribution you will notice that I see (and seek) possibilities to train as we operate. In the midst of townpopulation who's mindset "has been shaped" by, for instance, PsyOps elements. Although other operations which have more battle (non-permissive) characteristics can be trained at the TA's, it is still ONE operation.

If we brainstorm about this, supporting eachother to be creative, we will be able to set the conditions for an organisation that will be equiped for 3Block ops. Not stove piped elements, which will be organised in a modular way just before we deploy, but a permenant modular organisation in which all kinetic and non-kinitec elements and actors "experience" eachother. Such an approach will bring a broad perpective on the environment for all participants in a conflict.
I prefer "environment" above "battlespace" because battlespace refers to a specified area. Environment combines aspects like culture, economy, politics, opponents ... This is something for the Bn, Brigade level to be aware of.
