It can be really difficult on some maps where most of the ground space is cover and you have a 6-man squad. So the current version is the not the most optimal.
I'd like to use a counter argument to why this isn't the best idea. A sapper like cloak ability means that you'll have to toggle your units into cloak every time you wan that.
This is a valid point. So I would like to suggest the possibility of making cloak a toggle. So that when it's deactivated your infantry can cap like normal infantry and when it's activated they automatically cloak in cover.
The cloak modifier should also be taken a look at as it doesn't seem to give any buff (for Airborne, I am unsure about Luft) as it makes cloak somewhat useless and annoying. In a game that's constantly moving there has to be at least a small damage or accuracy buff for a short time out of cloak for an ambush to have any advantage. Support weapons tend to have long range and are easy to cloak where as infantry have shorter range and more men, which makes them more difficult to cloak. Hence why a small ambush modifier would make sense.
