Asthma and military basic training my current condition concerns about CS gas?

hello, correctly 18 years old in 5 days I'll be 19 I'm looking forward to see if i have what it takes to join the united states army i did a lot of research in regards of what to expect physically but i have been diagnosed with asthma at the age of 10..now, i have not had any problems with asthma that i need an inhaler, in fact i only used an inhaler on my first attack, my second attack was of the age of 12 no inhaler needed. I do get some symptoms but after being exposed to lets say a cat for days and the symptoms are very light no inhaler needed..the first time this occurred i was at my friends house celebrating the new years..i stayed at the house for about a week and only had symptoms on the 6th day..we didn't leaver the house much and the place is not very big...my concern is not exercise or long runs my concern is the CS gas..can i expect to have an asthma attack if i'm exposed to the gas for the short period of time they make the trainees go through it, if so how bad will the attack be, how long do you think it will last after i leave the chamber and is there a death march that you have to complete like in marines recon for graduation to become a part of an infantry unit. Thank you for your help
