The
communications specs for the Stryker Brigade, showing that it's all handled
by short wave radio and satellites, so the need for having 1.4 million acres
to train for an invasion of 1.4 million acres is NOT necessary.
The modern communications, touted by the Stryker spin meister, are such that 2 brigades could train at Fort Carson and at Fort Irwin, California, and be in complete communication, and in fact, would need to train on that "video game" aspect of modern military communications.
