I think this is where we need to start thinking differently about state on state conflict. State on state conflict is a distinct possibility and we need to figure out what it will look like because it won't look like World War 2. If such a war were to kick up and we fought in a manner where our infantry sections were getting consumed at the cyclic rate, where are the replacements coming from? Where is the industrial base to replace the lost LAVs, tanks, and fighters? It doesn't exist. We need to acknowledge that and develop war fighting concepts that ensure our infantry aren't getting chewed up.
Dispersion is also going to put a premium on the section. To survive in a conflict where we face an opponent who can both mass fires and use them with precision we need to disperse. We need to operate at levels that are, hopefully, below the detection threshold, and once found, hopefully the element is too small to be worth employing grid square removers on them. Hence why I've focused on the section. We need to leverage various robotic options to make this sustainable.
Offensively, I see two scenarios. One, we meet several conditions (air superiority, likely a lot of attrition of indirect fire assets and surface to surface missiles) and we launch on an offensive that would be fairly familiar to those of us who have studied history. For this, my infantry sections above are probably over enabled. The second option is that the enemy defends in a manner similar to what I've proposed above, in which case these infantry sections will have a variety of capabilities to help them infiltrate through the enemy defense and attack it from advantageous positions, thereby opening the way for a more rapid thrust that could quickly capture something vital.
