Came here to recommend this as well.
Such a great show.
You can torrent it, but the DVD box set can be found on Amazon..
Early on, their Captain is played by Kevin Conroy, the voice of Batman in the Animated Series, which is really cool.
Similarly, I loved Tour of Duty when it was shown back in the 80s/90s. My wife bought me the box-set a few years ago. No original music from the TV show, even the classic 'Paint it black' by the Rolling Stones theme tune was gone. I never got passed the first episode :(

Here is the Amazon US link for the Tour of Duty DVDs

Here is the Amazon UK link but you can see the description says "UK Import" and the DVD box cover says "Featuring the Original Music Including 'Paint It Black' by the Rolling Stones"

I normally look on amazon.co.uk or eBay for UK versions of DVDs.
These are PAL encoded and Region 2
The US is Region 1 and most of Europe is Region 2. In theory a DVD for Region 2 will not play in a Region 1 player.

Also the US uses the NTSC video standard while the UK uses PAL so that would not play either.
The reality is that you are on /r/datahoarder and these UK DVDs are just as easy to rip and convert to MKV files as any US DVD and play wherever you want.
The UK box set has all the original music. But you could probably still play it on most laptop dvd drives, since the dvd is for a non U.S. dvd players.
