Hi. My husband is in the army, so I can answer questions. The army is the land-based military branch.
What does he do in the army? 
Well, he's in the army reserves, so only really works during war or natural disasters.
I didn't know the army reserves assisted during natural disasters! 
Yep. Mostly they help with the  management of resources and responsibilities for dealing with all humanitarian aspects of emergencies.
That's amazing. Where has your husband served? 
He helped out after Katrina and did a tour of Afghanistan.
Tell him I said thank you!! What other services does the army provide? 
The reserves sometimes help out for big public events and stuff. Mostly helping with logistics. The army is very good at logistics.
I can definitely see that! Does he have to train every month?
