If you find yourself in trouble or just on a special mission with either a constant Alert phase or a neutralize enemies objective, throw them down and point the gun at them to make them "Freeze". This will force them to go into the ground hold up position. This approach is recommended, as you do not need lots bullets to force your way through the stage. Also, if the Alert phase clears you can see how many stars the soldier has to deem whether or not you wish to recruit them to your cause. From there you can leave them and continue, knock them out for items, recruit, or try the next trick. Note: A stage can only play host to a certain number of soldiers; if all the soldiers stationed there are alive, no more can come out to shoot you. This is perfect if you want to recruit just a certain soldier type on a constant alert map. Also if there is a wandering soldier in the Evasion (orange) or Caution (yellow) phase that spots your subdued enemy, they will be brought back to their feet and the Caution phase will be brought up or reset. Finally, if you have a large number of soldiers held up like this, make sure you do not fire your gun on empty. They may just get angry with you.
