During a midsummer tactical exercise, a company commander from the PLA’s 71st Group Army encountered an anomaly that nearly cost him the mission. Expecting the usual miles of grueling defensive barriers, Commander Qian found the 'Blue Force' obstacles reduced by nearly a third. What initially appeared to be a tactical oversight by the opposition turned out to be a calculated shift in modern Chinese military pedagogy.
Historically, 'Blue Force' units—acting as the opposing force or OPFOR—were encouraged to set obstacles as long and deep as possible to maximize the difficulty for the 'Red Force.' This 'difficult for difficulty’s sake' approach often resulted in unrealistic scenarios where engineers spent hours clearing 5-kilometer minefields that would rarely exist in actual theater operations. In this instance, however, the Blue Force commander traded static engineering for mobile lethality.
By shortening the obstacle depth, the Blue Force freed up significant manpower and firepower that would otherwise have been tied down in construction. Once the Red Force cleared the shorter path in record time, they were immediately met with a barrage of precision strikes and persistent harassment from multiple directions. While the Red Force eventually secured a narrow victory through sheer numbers, their casualties were unexpectedly high and their tactical rhythm was shattered.
This shift reflects a broader mandate within the People’s Liberation Army to move away from scripted, performative drills toward 'real-combat' simulations. Military planners are increasingly critical of training scenarios that ignore the constraints of time, terrain, and realistic troop ratios. The new philosophy dictates that obstacles must be integrated with active fire schemes rather than serving as standalone hurdles.
For the 71st Group Army, the 'Blue Force' is no longer viewed as a mere speed bump but as a 'whetstone' designed to sharpen the Red Force’s combat readiness. By simulating a thinking, resource-constrained enemy, these exercises are exposing critical gaps in command and control, battlefield perception, and tactical coordination that were previously masked by predictable, oversized defenses.
The leadership of the brigade now emphasizes that a 'win' for the Blue Force is defined by how many vulnerabilities they can expose in their counterparts. The goal is to move past 'over-the-limit' challenges that have no basis in reality and instead focus on the high-intensity, fluid nature of modern warfare. This evolution suggests a maturing military force that prizes tactical agility over rigid, quantitative metrics of difficulty.
