Ask your QM for a copy of the scale of issue that you are entitled to (should be D13011AA). It is available on the DIN at MA Reports Website. If you are entitled to Clothe the Soldier items as shown on that scale you should get them.
One thing to keep in mind, if you are on your BMQ, SQ, or DP1 training at Area Battle Schools or Gagetown, you are not entitled to Clothe the Soldier items. So as a Private Recuit if you got some, then you're lucky. It's not fair that some pers may have what they are not entitled to, while others dont have these items, if it really concerns you, bring that your chain of command. Your section commanders should sort this out with their troops so all pers on a recuit course/SQ have the same items, especially if they are from the same unit.
Do the other candidates on your course have them?
However, if you are entitled to the Clothe the Soldier items then...
Take the scale down to Clothing Stores and ask for WWB. When they say no, show them the scale and ask to see the authorization they have not to issue IAW the scale.
If the person at the counter gives you flack, take down their name, and for their supervisor. When the supervisor comes out explain the situation. If you are not getting any satisfaction take down the name of the supervisor, thank them for their time and return and explain the situation to your chain of command. Provide names and locations.
Always be polite, yes sir/no sir. Do not give anyone anything they can use against you. Take note of who was around watching.
But remember, be polite, you are Private, that doesn't mean that you can be denied your entitlements, but you are still a Private
Good luck, hope things work out.
