General Tips
When picking your sentry, choose based on mission type:
 * for defence mission consider taking EMS Mortar and some close-range sentries. It may be harmful to bring Mortar Sentry as on such missions there is not plenty of space to run around and kite; on extraction type missions citizens can easily get under its fire.
 * for operations on Terminid front close-range and horde-oriented sentries could come in handy, so consider bringing Gatling Sentry, Autocannon or Tesla Tower.
 * on Automaton front enemies you will have to deal with are much slower but tougher at the same time. As such, consider taking Rocket Sentry or Mortar Sentry with you. You could also bring Shield Generator Relay and use it to cover your sentries.
