Outside of maybe Russia and China I don't think any countries have the ability to detect launches, so from the military's perspective it could still be incredibly valuable to be able to send 100 soldiers as backup to a remote cave system in Afghanistan or wherever. On top of that, this could also have a lot of value even if it's only launched at US-held locations. Logistics can be a big deal: IIRC there were a few years around 2010 where the amount of money that the United States spent on air conditioning in Iraq and Afghanistan was actually larger than NASA's budget. The biggest part of that cost was in transporting fuel for the generators. If some of the worst convoy trips were replaced with rocket resupply missions you'd be potentially saving lives and money.
