So my thought on heal delpoyment would be med kits of some sort for group heals and defense area heals. As for indiviual heals maybe some thing like a syringe which would also double as a revival tool like adrenaline to the heart(Pulp fiction anyone).
As for body type I plan on playing Medium build and my reasoning behind it is simple I think it would provide the best balanca between being able to take damage and mobility; you wouldn't be able to die like operatives but you would be able to out run a heavy were you to find yourself in that situation.
as For weapons I still plan on running with an assult rifle or maybe even an SMG.
None of the above is fact and all of it is strictly speculative.
