Realistic combat training – train as you would fight
Dembiński quotes the maxim he heard from older colleagues after joining GROM: 'train as you would fight'. He describes how the aggressor team arranged ambushes so creatively that they seemed impossible in a real fight — and yet the guys fell into them. When the commander wanted to prove to another unit that he wasn't going easy on his own, he invited them to watch the OPFOR. After it ended, they said: 'No, well, you did go easy on us after all'. Thanks to this culture, Dembiński himself, entering rooms with charges, had a 'one-to-one replication' of real combat. The effect was confirmed when he was hit by three bullets: no one from his team gave up, everyone executed the procedures 'just as we were trained'. He notes that working with FX and constant exposure to high-fidelity simulations means that 'I practically did a 1 to 1 reflection'.
Training in combat-like conditions encodes procedural memory sequences so deeply that under extreme stress inhibiting the prefrontal cortex, the soldier relies on learned patterns, not conscious analysis.
As a wounded man in the fight, he saw that his section mates did not deviate from procedures, even though the enemy kept shooting; the whole team acted as in training, which saved his life.
Train as you would fight. The more sweat spilled, the less blood in battle.
