sort of. you cant disembark out of most ambient buildings the same way you would a garrison. but you should be able too select the emplacement itself and it has an ability- trying to click on the squad will just select the emplacement as a whole, which is sorta buggy, but it should be possible to still disembark from emplacements, just annoying. although being able too select the squad within the garrison properly would be nice and fix the bug.
