They can bribe any enemy unit that is adjacent to Vegas's HQ to make it attack another unit. If your units attack Vegas HQ, you can not be sure when they will stop attacking Vegas and turn to attack you! The other army is a SMART, spreading fear the army of half machines, half-mutants, the experimental hybrids are transported in sealed combat transporters to battlefield where they emerge and destroy everything that moves. These are an extremely deadly force. Every ally adjacent to Smart's HQ has the ability to move. It makes this army very flexible and dangerous.
