Quite so.

Rather off the thrust of this thread, but occasionally the British trend for naming army kit is so apt as to be uncanny; some farsighted person in Alvis I deduce saw this coming and managed to stake off the S names it seems for Alvis alone.

Now I'll probably miss some, and some may not be instantly recognised although a Google with Alvis as a "prefix" will do, the name and vehicle application/nature is almost perfect:
Salamander, Saladin, Saracen, Stalwart, Scorpion, Striker, Scimitar, Samson, Sabre, Spartan, Samaritan, Sultan, Stormer, Shielder, Scarab and likely some I've missed.
