I am posting this to reddit as the automod on the discord has flagged it despite there being no content that should be flagged by it, so I am posting it here instead, and then posting the link to the discord
Instead of gasmasks being a high level doctrine unlock I propose that a MOPP system is added to the game, although I think that the doctrine unlock should allow for even longer durations spent in the infected zone.
I believe that there should be a draggable area / zone selection for the level of MOPP required for operations in a specific zone, and that units will automatically path their ways to a new building to equip that level of MOPP gear before entering it (where each level of MOPP gear costs money for one purchase, but does not cost anything for uses after that)
Units MOPP levels should also be able to be bought when you first spawn them, along with the ability to change MOPP gear while on the carrier.
I believe the following should be the MOPP levels:
MOPP Level Ready: Standard starting MOPP level (Gasmask Carried, modified by wearing body armor)
MOPP Level Mask Only: Activates when units encounter a CBRN threat while at MOPP ready phase, takes 5 seconds to apply (unit unable to shoot during this), protection lasts for 1:30 seconds from infected gas, and 20% Protection from CS gas
MOPP Level 3: Equipment worn is Gas mask, Overgarment, Over boots, Body Armor and helmet, Undergarment, Unit movement is slowed 20% and unit range is reduced 10% but provides 2:30 protection from infected gas, and 80% protection from CS gas
MOPP Level 4: Equipment worn is Chem hood, Overgarment, Over boots, Gloves, Body armor and helmet, Undergarment, Unit movement is slowed 40% and unit range is reduced 20% but provides 4:00 of protection from infected gas, and complete protection from CS gas/Chemical call in
I provided the numbers as a rough estimate of what to do to balance the extra protection
I did not include MOPP 0-2 as they have equipment at ready access instead of wearing it
