Sure, but we have problems there too.
Firstly, we have severely limited number of satellites (of any kind, including civilian). Believe it or not, the UK with no independent launch capability of its own has more satellites currently in orbit than we do.
We have a grand total of 1 geostationary satellite providing services to the whole Indian Navy, and that's not even a High-Throughput sat (HTS) and one has to wonder the bandwidth limitations for how many concurrent transmit/receive requests it can fulfill. The GSAT intended for Army lost contact and far as I can recall, no replacement has been launched yet.
Not to mention sats in GSO can be limited by line-of-sight due to being fixed point in sky and can be restricted due to terrain & high mountains (provided one is using some form of satphone terminal type device).
What we need in order to ensure unimpeded secure satellite-based high bandwidth two-way communication for troops on the group would ultimately have to be our own version of something like Starlink in Low Earth Orbit, owned & operated by the newly formed Defence Space Agency (DSA).
Currently, if you want large-scale guaranteed secure comm without breaking the bank, its far cheaper to just run a RAN network, with only a few SATCOM uplinks somewhere in the loop.
I've heard of this, but have no idea how secure or repeatable it was (or what they were using), or if they were lugging around some form of manportable SATCOM terminal - and if so then what satellite they were communicating with (Indian or foreign, military or piggybacking on civilian) and how secure that was from eavesdropping.
True.
For the simplest look at how these support units work one can see the units that UKSF is comprised of:

I have to assume a large part of why these courses aren't conducted is the typical turf war mentality among the brass of the various services. Unfortunately I don't see much improving until & unless we have theaterization of the forces across the board, and the new C&C regimens become mandated by law.
