I suggest removing separate the strategic mode, and moving it's UI into the tactical mode. This would give the same functionality without switching modes, and without all the loading that follows from that.
And as you think why we did not this?
From harm, or maybe because there were some reasons?
Also, let me choose colors for the unit icons and location markers. It's confusing with russians having blue unit icons, but red location markers. It would be better if we choose from a range of colors for each side, and have the same color for units and locations imo.
A common system: the blue is _always_ enemy, the red _always_ allieds. And it will remain forever.
Everything else is unreliable and ambiguous, especially if several sides involved.
For example, what color are Afghan Mujahideen? And if they fight against Iranian troops? And if the enemy is Iraqi?
Try to answer these questions and your offer will disappear by itself
